MPLS issues with redundant PE routers
Hello,
i'd like to set up an mpls lab. the layout of the gear is attached (mpls.jpg) At site A i have to PE router R4 and R6 which should have knowledge of the network 10.0.129.0/24 from site B. Router R1 is configured as a route reflector. the configuration of R1, R4, R5 and R6 are attached as well.
with the configuration
Routing Table R6
O E2 10.0.129.0 [110/1] via 172.16.128.9, 00:04:37, FastEthernet0/1.200
Routing table R4
B 10.0.129.0 [200/11] via 150.1.5.5, 00:05:00
a traceroute shows the path goes through R4 instead direkt through R1
Tracing the route to 10.0.129.1

any ideas what i have to do in order to have a redundant path towards site B?

Hi Alex,
I think you still have redundancy via R6, but BGP route on R6 is not getting installed in routing table because it is having OSPF route with lesser AD value. If R4 goes down, R6 will loose OSPF route for 10.0.129.0/24 coming from R4, install BGP route ,redistribute this to OSPF and will advertise it to SW4.

Hi:
This post is for those that have the below listed Atheros adapters, and recently upgraded their routers (usually from a Wireless G to a Wireless N router from 2009 or newer), only to find they cannot connect to the internet anymore.
Atheros AR5006 802.11a/b/g WiFi Adapter
Atheros AR5007 802.11b/g WiFi Adapter
Atheros AR5009 802.11a/g/n WiFi Adapter
When using their old equipment, there were no problems.
Symptom: When upgrading to a new router, normally connection is made to the local network, but one cannot access the internet.
Symptom: Wireless connects if using WEP security or no security, but will not connect when using WPA2-Personal security.
For those who have the above Atheros wireless adapters, and are experiencing issues with connecting to the internet, there is a driver available that should remedy the situation.
It is good for Windows operating systems -- Windows XP through Windows 7 -- 32 or 64 bit.
It may work on Windows 8 too, but I haven't tested it on Windows 8.
Here is the link to the driver download page:
http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=5060881&swItemId=ob_108905_1&swEnvOid=405...
Best Regards,
PaulI created an HP account just to thank you for this link. I've spent 2 days online and talking to call centers trying to get this driver. I was finally going to just return my router to Best Buy. Thank you SO much!

Anyone else having issues with third party routers...
Last week I started having issues with my Asus RT-N66U where certain wireless devices e.g. PS3, Xbox 360, Laptop, etc. have issues connecting to the internet (the PS3 reporting a DNS issue) even after I replaced it with a second rt-n66u.
I then tried using the HH3 I got with BT and have none of these problems.
Back on the Asus I tried a manual DNS (BTs 62.6.40.178 and 62.6.40.162) but these are having issues as well although strangely it will work fine if I use it purely as a wireless access point via the HH3 (With HH3's internal wifi disabled), right now I'm testing it again with Google's DNS but I want to know, is anyone else having any issues?Is your firmware up to date? http://support.asus.com/Download.aspx?SLanguage=en&m=RT-N66U+%28VER.B1%29&os=8

Issue with 2wire dsl router when connecting power pc g4 via ethernet
Issue with 2wire dsl router when connecting power pc g4 via ethernet. The 2wire will keep resetting. When I connect my macbook pro via ethernet to the 2wire all is ok, but as soon as i connect the power pc. . . .reset. I have emailed 2wire support. They recommended using a different patch cable. Tried that.. .. anyone else having this issue???? Any help would be appreciated. . .
Search the discussions for issues with 2wire dsl routers. This has come up before in a discussion I've been involved with, but probably not to do with the MDD. I do remember it being a design issue with the router, something that was done to it before dispatch.
Let us know if you can't find it and we'll have a look.
If you afford it, bin the 2wire and go buy something decent like a Netgear. -
Windows 7 Update Internet Connection Issue with Router
I updated two of four toshiba laptops with Windows 7 and installed Toshiba's wireless adapter driver for Windows 7. The adapter connects to the router and I can access all resources on my home network, however, Internet service is not available on the two laptops with the Windows 7 update. After disconnecting and reconnecting 7-10 times, the Internet Service connection does not drop. The other two laptops and two desktops that are not running Windows 7 do not have this problem. Is there any known issues with lynksys wireless routers and Windows 7?
When your Windows 7 machine is having problems, can it ping the following IP addresses:
127.0.0.1 (local loopback)
192.168.1.x - the DHCP IP address it was issued by the router
192.168.1.254 - your router
8.8.8.8 - Google DNS out on the internet

I have a new iphone 5 and I can't pick up a wireless router that I could use with my old iphone 3GS. Is there an issue with the new iphone and is the antenna weaker than the 3GS?

Re: Anyone still having IOS 6 wifi issues?
created by mpa9366 in Using iPad - View the full discussion
Having done a lot of reading today and having found a very good online tablet magazine (will post link tomorrow) there seems to be a few tech bods onto the problem.
The magazine I was reading identified wifi problems within hours of the ios 6 release and have been analysing since then with almost daily updates - the story seems to be:
The apple authenthication transmission is normal, it should slip through event prior to a full handshake with the host network being completed - however if not authenthicated then apple will not permit the device to connect (kills the connection) this is designed to protect apple from counterfeiting. So thats problem 1 if you dont receive a token from apple.
Problem 2 is that ios 6 only supports ipv6 (the new ip protocol) whereas outside silicon valley a large proportion of routers modems etc are still ipv4 protocol.
So youre locked into ipv6 in a world where ipv4 devices are everywhere and apple have not allowed for the ability to handle both protocols. This is like GM telling you your car requires an upgrade, everything will improve etc and as part of the upgrade fits a fuel cell motor and stays silent when their upgraded vehicles are simply parked up because they cannot get fuel.
A very basic expectation would have been dual protocol handling - we know the HW supports ipv4 as all wad fine on ios5.
So its going to be hit and miss with networks - more hit than miss in techy areas like silicon valley, but more miss in places like where I am - a small town in rural Switzerland.
Only apple can fix this with a patch to enable ipv4 protocol handling.
There you go. you just need to buy a new router, I'm sure Apple has one for sale, cause it's not there fault for sure.
Wonder why people start to migrate to other devices ? -
10.4.8 network issue with some routers (Zyxel)
Since I have installed 10.4.8 there is a problem with my Zyxel Prestige 310 router, which after a short period of time "hangs up" - so nobody in the network has Internet conection ( PC's and other Macs with 10.4.7).
After restarting the router everything works fine, until I start a Mac with 10.4.8..
This happens on Intel and G5 Macs..
Today I had a long phonecall with my Provider here in Austria, who told me that a lot of people are having this problem - all with Zyxel Routers - but he doesn't know a solution.
He (and me) is waiting for a fix from apple...:-)I also have an issue with the 10.4.8 update and a Zyxel router, although mine is not as severe as yours.
Mine has to do with WPA encryption and a timeout setting.
The thread is here:
http://discussions.apple.com/thread.jspa?messageID=3246932
So, maybe this helps?

Apple Support admitted an Issue with WEP authentication and some Routers
After reading many posts here and other places I logged a service call to Apple support. With the particulars: AT&T U-verse 2 Wire router would not connect with WEP would connect with Security disabled. I wanted a call logged before I went past the return time
I got a call back immediately after a few basic questions I was passed to a product manager for ipads, it seems connectivity issues are taken seriously.
The upper level support said there were known issues with some routers and WEP security we steeped through changing the security and it works fine now.
Bottom Line:
Apple knows there is an issue with some routers
They were very helpful and acknowledged the issue.
He even stayed on the line while I reconfigured one of my Windows PC to make sure it connected to the new settings
I suggest to all to log a call and get a tech support involved before taking the iPad to the local store
They certainly new their are some connectivity issues. If that does not work you can always return it.
He did not admit it was a Apple issue and did not commit that Apple was working on it but it is something they are aware of.
So skip the Apple store got right to tech support.
Just my 2 cents."But folks need to go straight to tech support. I live in oz, so it will be interesting to see if they help me.. or not.. but if support gets inundated they will fix it or have a massive recall (not likely on the latter)."
Can't agree more. I used to manage a tech support department and it is all about the numbers. No matter how many forum entries the issues that get addressed are dictated by the reports.
So for those that are buying new routers contact Tech Support first even if you end up getting a new router the call is logged that will get Apple's attention.
People that are not familiar with post launch processes have no idea how things that need to get corrected and enhanced are dictated by support requests -
I have a wireless home network consisting of a time capsule, two airport expresses and a cable modem. Even with this configuration I get a very weak signal in much of be condo - the walls, etc. are solid concrete. I want to see if I can add another separately connected cable modem and connect one of the existing airport express to it by Ethernet cable. If so, this would give me two wired hubs and greatly improve signal strength. I do not know if this configuration will in fact work or if I will just wind up with two, separate and unrelateable networks. Unfortunately, there is no way to run any additional Ethernet cable and I doubt simply adding more Airport Express will help. Thanks.
Try Ethernet over Power adapters.. these are very popular for your kind of environment.. being able to make non-wireless link to another area where you can setup a wireless access point.
Airport Express are not great for wireless power.. if you really have issues with wireless strength in a bad environment apple stuff is not the way to go.
The comparison chart here.
http://www.smallnetbuilder.com/lanwan/router-charts/bar/58-2_4-ghz-dn?see=P_F
This is their worst test location you can also see averages.. the latest airport extreme.. is there a long way down.. and that is a much better wireless device than Airport Express.
The Ubiquiti power AP is small cheap and designed for precisely this duty.. useless in an apple wireless network.. you will need to run ethernet or EOP adapters back to the main router.. but if the normal omni directional antennas don't provide enough signal you can get directional ones.. I suspect you can cover your whole apartment with a pair of these and high gain directional antenna. -
When using my web e-mail (Outlook web app) Safari frequently closes the page and says it must reload the page...then it errors-out. When this happens I must close Safari completely then reopen it, and reopen Outlook web app. My cache is cleared frequently (at least once per day). I am also unable to directly attach docs to e-mails - I must go the through the process twice. This never occured before Mavericks.
Any ideas on a solution...anyone else experience issues with Safari/Mavericks operations?Hello Cabamyk,
It sounds like you are having issues loading this web app for Outlook. I was thinking that there may be a 3rd party add-ons interfering with Safari or perhaps one may need to ge re installed. Use this article to help troubleshoot add-ons:
Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues
http://support.apple.com/kb/ts3230
Use the add-on's uninstaller, if possible
Quit Safari.
Remove any unsupported third-party add-ons you've installed (see if the add-on's installer includes an uninstall feature).
Open Safari again.
If these steps fix the issue you were having, check the website of the software's developer to see if there is an updated version available, or avoid using the add-on.Manually uninstall third-party add-onsIf the software doesn't have an uninstall feature, quit Safari and try manually moving the third-party add-on files. These files are usually installed in one or more of the following locations:
/Library/Internet Plug-Ins/
/Library/Input Methods/
/Library/InputManagers/
/Library/ScriptingAdditions
~/Library/Internet Plug-Ins/
~/Library/Input Methods/
~/Library/InputManagers/
~/Library/ScriptingAdditions
The first four locations listed are in the root-level Library on your hard disk, not the user-level Library in your Home folder.The tilde (~) represents your Home folder.
To access the Home folder in OS X Lion, OS X Mountain Lion, or OS X Mavericks, open the Finder, hold the Option key, and choose Go > Library.
To access the Home folder in Mac OS X v10.6 and earlier, open the Finder and choose Go > Home. Then, click the Library folder.
If the issue is resolved by removing items from the above locations to a different location, return the items one at a time and test Safari. That way you can determine which item is causing the issue. Once identified, remove the problematic item and put the others back. Check for updates to the items that are found to cause issues, or report the issue to the add-on developer.Important: When removing items from the above locations, do not put them in the Trash. Instead, put them in a new folder or on the desktop while troubleshooting. If removing the item does not resolve the issue, you can put it back where it came from. In Mac OS X v10.6 or later, you can use the Put Back feature of the Trash to automatically put items back where they came from.Files that should not be removedThe following items should not be deleted from your system:
/Library/Internet Plug-Ins/iPhotoPhotocast.plugin
/Library/Internet Plug-Ins/nsIQTScriptablePlugin.xpt
/Library/Internet Plug-Ins/Quartz Composer.webplugin
/Library/Internet Plug-Ins/QuickTime Plugin.plugin
/Library/Internet Plug-Ins/QuickTime Plugin.webplugin (Mac OS X v10.5.x only)
/Library/Internet Plug-Ins/VerifiedDownloadPlugin.plugin (Mac OS X v10.5.x only)
Reinstalling the above plug-ins requires reinstalling OS X. Some application or system updates may restore specific plug-ins.
Thank you for using Apple Support Communities.
All the very best,

Calling issue with Cisco 7937 conference station
Hi Friends,
I am facing issue wiht Cisco 7937 conference station, our customer have various branch offices accross the world. All branches are connected over MPLS through service provider( SIP service provider) . there is a centralized CUCM and remote office have SIP Voice gateways .
When making calls from once remote site to another using Cisco 6921 phones calls working fine
When making calls from once remote site to another using Cisco 7937 conference station to make call any phone at remote office, calls are getting disconneted, remote phone rings when calls, but its gets fast busy tone when other party picks up the phone and not able to talk.
I suspect the issue with Codec but we have configured transcoders in VG and registered with CUCM
Please help me if any one experience such issue earlier.
Regards
Sivahi Basant,
1. Actually tow phones A and B are registerd with centralized CUCM, A and B are located in two different locations, RTP traffic between And B pass through service provider.
Call Flow --> Phone A ---->CUCMRouterpattern--> SIP trunk ----> Voice gateway--->Service provider cloud---> Respective Voice Gateway---> CUCM -- Phone B

MPLS, GRE (with no IPSEC) & Dynamic Routing
Good day my friends!
Just wondering if any of you could help shed some light on how I would do something. We are switching over from a Point to Point connection between sites to an MPLS one. I have read that Multicast is not permitted across MPLS, so after terminating the MPLS circuits into our network, I created some GRE Tunnels to allow for Multicast (for Dynamic routing as well as Music on Hold)... Everything went well, other then all traffic between the sites is going over the Tunnel interfaces. I would prefer that only multicast traffic go over the GRE tunnel and all other traffic traverse the MPLS without GRE Encapsulation.
I attempted to do this by doing the following... I wrote an access list indicating Multicast source addresses, then created a route map and did a match ip address acl and set interface to tunnel. then I applied that route map to the vlan (although it doesn't give me the option for direction on the 6509 switch) that the single interface is a member of. That interface goes to the router provided by the service provider. I did the same in the other site as well (2811 router, appied to the interface). What have I done wrong so far?
We run EIGRP and I did inject the tunnel ip addresses into eigrp, after which traffic started going across it (the tunnel). I need to make sure that routing can find a path via MPLS in EIGRP outside of GRE, and for that all I have done so far is create static routes (on our 6509 and 2811 devices that the MPLS terminates to) with the destination subnet being in the other site between the qwest router and our router (Did that at both sites). I havent created any static routes for remote sites internal subnets because I would like EIGRP to do that, I don't want to rely on Static routes for routing between sites as far as our internal routing.
So I guess, my question is 2 fold:
What else do I need to do to get EIGRP to know about the path between sites over MPLS besides through the GRE tunnel?
How would you control traffic so only Multicast traversed the GRE tunnel where all other traffic would go over MPLS natively?
Any help you could lend would be very much appriciated!Thanks for the reply Laurent!
Ok, so I just got off the phone our SP and they said they do not support Multicast transport over MPLS... so your assumption is correct...
I see, so it sounds like I want to stay away from allowing all traffic to traverse between sites over MPLS via GRE... I never considered the issue with scaling when using GRE for all traffic. Good to know!
While I was on the phone with our SP, I talked with them about routing protocol's they support via MPLS, to which they responded with BGP as really the only option.
FYI, this is our current WAN arrangement between 2 of the sites:
Site A>Cisco 2811>Adtran Router (SP provided)>PE-PESite B
Site A>Cisco 2811 (same as above)>Adtran Router (SP provided)>PE-PESite B
The SP suggested we run OSPF between our hardware and the Adtran routers and then 2-way redistribute subnets between EIGRP to OSPF and then from OSPF to BGP as follows:
EIGRP ran inside Site A and B
OSPF running on outside facing interface on 2811 and 6509
OSPF running on inside interfaces on Adtran routers
Private AS BGP running on Adtran with Public AS neighbor to PE device
This should work, but wouldn't it work for me to just configure BGP on our 2811 and have a IBGP adjacency between it and the Adtran Router and then filter what routes are redistributed from and to IBGP on our 2811 into EIGRP? If this would work, does one design have any advantages over the other? It seems like the EIGRP to OSPF to BGP idea has to many moving parts...
My objective is to allow all devices in all locations (4 MPLS sites) to route dynamically, verses relying on static routes.
Regarding the Tunnel config's... I see... Excellent example. OK, so it sounds and looks like I would first configure each site with the routing protocol solution, then, implement GRE with per the example provided, and that would accomplish Multicast over GRE and everything else over MPLS! Thanks alot Laurent!
So what would you recommend regarding the routing protocol structure? -
Multiple Issues with Adobe Creative Cloud app.
I'm having multiple issues with the Adobe Creative Cloud app.
1. Neither Photoshop CC nor Prelude CC get past the 47% mark when installing. They constantly give me "Installation Failed" messages. When I click on "Learn More", I'm told that:
"Installation Failed
Errors during Installation.(7)
More Information"
So naturally, I click on More Information to get the following thrown at me (none of which I understand):
Exit Code: 7 Please see specific errors below for troubleshooting. For example, ERROR: -------------------------------------- Summary -------------------------------------- - 0 fatal error(s), 2 error(s) ERROR: 12/01/13 13:16:06:425 | [INFO] | | OOBE | DE | | | | 6076 | ---------- CustomHook_Helperx64 ---- Start ---------- 12/01/13 13:16:06:426 | [ERROR] | | OOBE | DE | | | | 6076 | Cannot load function name 'CSInstallerCustomHookProc' from library C:\Program Files (x86)\Common Files\Adobe\Installers\uninstall\{5F816B76-62F3-41C9-B651-27F49F25F50B}.data. Error 0 ERROR: System check returned with error : -4 -------------------------------------------------------------------------------------
2. I installed Lightroom 5, then uninstalled it. When I went back to re-install it, the Adobe Creative Cloud app wouldn't let me. It states that my Lightroom 5 is "Up to date" and is in my "Your Apps" section, not in the "Find New Apps" section. I've double checked my Programs and Features in Control Panel, and it's not there. I cleaned my registry, and it's still there. I deleted the "opm.db" file in my OOBE folder, and restarted CC - still nothing.
I've got to say, guys. I'm not very happy with the amount of time I've spent just trying to install programs on my PC. While the plan is for this to be intuitive at some point, it's not very functional at the moment. Any help you can provide me would be amazing - if you can provide it sooner than later, I'd be over the moon.
Thanks.I fixed it. I fixed it on my own. My journey took over a week (forty hours of back and forths, trial and error, and service!!) and included multiple calls, multiple online chats, unanswered forum posts, Twitter conversations with the Adobe Customer Service team, remote access sessions with Adobe technical teams, and finally this series of emails. In the end, I had to figure it out myself. I'm not happy - not with the time it took, and not with the level service I received based on the urgency that I made clear.
For anyone else that had this issue (or similar), here is what I did to fix it. This may seem excessive, but that's because I didn't know what else to do. Some of these steps may be redundant, or not required... but I wouldn't know because once I saw that it was working, I just kept going.
Anyway, here is the solution I came upon (I'm running Windows 7 64-bit):
1) I uninstalled every single Adobe product (including Flash Player, Acrobat Player, Air, and Digital Editions).
2) I ran the Cleaner Tool (which is not very good) and came across errors in trying to delete certain folders.
3) I restarted my computer in Safe Mode, and logged into Windows 7 under my Administrator account.
4) I manually went into every folder that contained the words "Adobe" and deleted everything. This includes my Program Data folder, my Program Files folders (both x86 and 64-bit), my AppData folders, my Roaming folders, my Temp folders - ANYTHING and EVERYTHING that contained any trace of Adobe, I deleted.
5) I ran Microsoft Disk Cleanup and Piriform CCleaner to clean my registry and temp files.
6) I restarted my computer using the normal boot process and logged into Windows as Administrator.
7) I downloaded the Adobe Creative Cloud installer.
8) I restarted my computer again, and logged into Windows as Administrator.
9) I ran the Creative Cloud installer, and installed Premiere Pro.
10) I restarted my computer again, and logged into Windows as Administrator.
11) I ran the Creative Cloud installer, and installed Photoshop.
12) I restarted my computer again, and logged into Windows as Administrator.
13, 14, 15...) I ran the Creative Cloud installer and installed whatever programs I needed, then I IMMEDIATELY restarted my computer before installing anything else.
Hope this helps. Good luck! -
Windows 7 Pro DNS issue with static IP
0
down vote
favorite
I have been unable to solve a DNS problem I am having as follows:
I have a Windows 7 Professional (64 bit) computer running VirtualBox with a couple of Windows XP guests (not sure if this bit is relevant). After heavy file copying/transfer on both of the Windows XP machines, both the guest machines AND the host loose anything
DNS related, so I cannot call anything by name, but by direct IP works fine. The only resolution is to reboot the (host) machine and it will then work OK for a while until it happens again. The only trigger to make it seem to happen quicker is to re-initiate
the heavy file transfer and this then causes the DNS resolution to stop working again.
The machine has a fixed IP address, so it isn't related to DHCP.
I've tried the machine connected wired and wireless, no difference.
The IP settings are manual and I have tried giving it the DNS settings of the router (normal settings) and I have also tried giving it Google's DNS servers (8.8.8.8 & 8.8.4.4). No difference.
It seems to happen (sooner) during heavy traffic.
Other Windows 7 machines in the network work fine (though they are Home version, not Pro).
ONLY DNS fails, direct IP works OK.
Reboot seems only solution at the moment.
I am now lost as to what to try to resolve this issue, I do not really want to reload Windows 7 as it is a relatively new install... I have read about issues with wired connections on my router (BT Home Hub 2.0) so tried a wireless connection, still the
same.
Here is my ipconfig /all (it shows the BT Home Hub router DNS settings, but it also failed with Google's 8.8.8.8 and 8.8.4.4 entered here and also with the routers 192.168.1.254 (default).

Any ideas where to look, or what other info to provide for any assistance?
Many thanks in advance.Hi,
This has just happened again, here is the content of the netstat results as requested...
If I kill the VirtualBox virtual machines, it starts working again. It is as if there are no ports left, but I am not occupying that many? Surely Windows 7 can cope with this?
I feel I am missing something important, but cannot put my finger on it...
Further below, I have re-run the netstat command AFTER I have closed the VirtualBox machines and the system works OK.

Issue with instant ringback when using sip trunk to SP
Hi all,
We use CUCM 8.0.2.
We have a SIP trunk to a SP connected via one of our Cisco 2911 routers configured as a CUBE.
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.0(1)M3, RELEASE SOFTWARE (fc2)
c2900-universalk9-mz.SPA.150-1.M3.bin
Cisco CISCO2911/K9 (revision 1.0)
Technology Package License Information for Module:'c2900'
Technology Technology-package
Current Type
ipbase ipbasek9 Permanent
security securityk9 Permanent
uc uck9 Permanent
data None None
We also have several ISDN lines that run out via various Cisco routers configured as H323 gateways.
We use 7945 and CIPC for our phones.
We're having an issue with calls going via the SIP trunk where we hear ringing instantly after dialling - but before the actual device at the other end starts ringing (considerable difference).
Using the SIP trunk: If I make a call to my mobile phone - I hear ringing instantly - about 3 rings before my mobile phone actually starts ringing - undesireable.
Using H323 gateway: If I make a call to my mobile phone - I hear silence for a bit - then ringing when the mobile starts ringing - desired.
Using SIP trunk: If I make a call to a landline that is ready - it rings instantly for at least 1 ring - before the actual phone I'm calling starts ringing - undesireable.
Using H323 gateway: There is a momentary pause before hearing ringing on my phone and the phone I dialled - desired.
Using SIP trunk: If I make a call to a landline that is off-hook (with no call-waiting/etc.) - it rings once and then returns the busy signal (the worst issue) - undesireable.
Using H323 gateway: There is a momentary pause before hearing busy signal - desired.
Phone to phone internally (same network): Operates as expected (instantly rings locally and on the phone I'm calling). Between phones that utilise the SIP trunk and phones that utilise the H323 gateways within the same network - communication is instant and as expected.
Any ideas why this happens and how to stop it?
I want it to not ring until the situation is known and that it can provide the appropriate feedback (ringing/busy/etc.).
Some possibly relevant config (note that there is a known bug with this IOS that meant I had to declare the codec in each dial-peer as the voice class would not work):

Any help or a point in the right direction would be greatly appreciated.
Cheers,
BrettI ended up resolving this issue as follows:
In CUCM, under Device > Device Settings > SIP Profile.
I modifed the profile relevant to my SIP trunk, under the "Trunk Specific Configuration", I set "SIP Rel1XX Options" from "Disabled" to "Send PRACK if 1xx Contains SDP".
Now, I get the expected delay before hearing ringback.
Solved!
