Remote C2901 MGCP gateway won't register with CUCM

Hi, all,
We have a central call manager, we are setting up a remote office with a C2901 voice gateway that has a T1 PRI, this gateway is being configured as a H.323 gateway, everything worked fine. Now I want to get SRST working such that when WAN goes down, employees can still make outbound calls and take inbound calls. I followed SRST documentations when configuring CUCM and C2901, I would say the documentations are clear and easy to follow -- only thing is there is no adequate explanation of why those commands need to be there and I can not get SRST to work.
1), First, a basic concept question, why do we need to configure "ccm-manager fallback-mgcp"? or any MGCP related configuration on C2901? how does MGCP play the role in SRST? the router is configured as a simple voice gateway, when WAN is intact, we use H.323 protocol, when WAN goes down, we still don't need MGCP ...
2), Assuming that we needed all those SRST related MGCP configuration, I would expect C2901 to register to call manager, but I could not get this device to register as a MGCP gateway, debug mgcp packets shows:
*Sep 5 16:52:47.571: MGCP Packet sent to 10.128.181.5:2427--->
RSIP 201356931 *@voicegw-remoteoffice.local.domain MGCP 0.1
RM: restart
<---
*Sep 5 16:52:47.631: MGCP Packet received from 10.128.181.5:2427--->
500 201356931
<---
I verified the domain name is exactly the same as the name configured on CUCM, I tried multiple time toggling ip domain name on C2901 also, somehow CUCM does not like RSIP message from C2901, I don't have knowledge to get debug information from CUCM side of why CUCM does not like the MGCP message sent by C2901
3), When the communication is blocked from C2901 to central call manager (by using a simple ACL on C2901's default gateway device), I can still make the inbound call to an IP phone, which means, phones were correctly registered to C2901 when communication to call manager is broken, but I can not make outbound call, phones always get quick busy beeps, test call from C2901 itself (by using "csim start") is fine, which means dial-plan and ISDN/PRI is fine.
I believe we are just doing very very basic configuration and this is a common scenario, what could I do wrong?

You dont need the mgcp related commands if you are using H323. The commands that you need are:
application
global
service alternate default
call-manager-fallback (or) telephony-service and the relevant commands under it.
Also make sure that SRST reference has been added to the DP and the phones reset after the change made. This is what tell the phone to register to the SRST gateway when the WAN is down. The IP specified in the SRST reference should match whats configured under call-manager-fallback.

Cisco 877 router - Cisco IP phone won't register with SIP provider

Hi all,
I'm having a problem with a Cisco SPA504G phone not registering with the SIP carrier over the Internet. We've recently rolled out a Cisco 877 router onto a new NBN business connection and can't get the pre-configured IP phone to register.
When we tested the phone with the NBN-provided Netgear router, it worked fine, as it did with the previous Cisco 1841 router we were using on a different link.
The way it's setup is using VLANs to define the internal subnets, which are then assigned to the physical interfaces (since the 887 doesn't allow IP assignments to the interfaces directly).
VLAN 100 is the internal network and has a SBS2011 server – assigned to F0 – IP range is 192.168.1.0
VLAN 200 is the guest network and has Internet access only – assigned to F1 – IP range is 10.1.1.0
VLAN 500 is the WAN network and connects to the NBN upstream box – assigned to F3 – external IP address assigned by DHCP
I've been playing around with access lists, nat rules, basically everything in my limited Cisco knowledge to try and figure this out, but to no avail. I have even configured what I believe is unrestricted access to IP, UDP and TCP outbound and inbound to all VLANs and still can't get it to register.
Tried isolating the issue by creating a new VLAN and assigning it to the spare interface and basically allowing everything in and out, but still no luck.
The problem has to be something on the router – probably some small line of config I haven’t removed or added.
I am going to pull my hair out soon, so would really appreciate some assistance from the Cisco gurus out there.
My client has just purchased about 10 of these handsets from their provider so I need to fix this ASAP. The guy who provided them wasn't very helpful, and basically said I'm on my own once we tested using the NBN-provided Netgear router.
Happy to post my config as well.
Please help!!!!

My iPod said that it needed to do an update but halfway thru it stopped and said there was an error and now it's stuck with the apple and an empty loading bar. Also it won't register with my computer. Help?

I plugged in my iPod and it needed an update. Before the update could complete it said there was an error and then closed the window. Now my iPod is stuck in the loading screen and won't register in iTunes. Please Help.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Hard Drive won't register with FCP X

I'm new to FCP X and I want to use my hard drive with it becuase i'm running out of space on my computer.
But my harddrive isn't registering with it. It shows up on my computer and i can read and write on it but it wont show up in FCP X
I don't know what to do! If i can't figure it out i think i'll have to start deleting files on my computer

Also, can you provide your current system specs (including external drive.) Clearly you're not running 10.4.

Cisco Jabber for Mac 9.2.1: slow to register with CUCM

Hi,
We have this specific problem on our Jabber for Mac 9.2.1 client only: the client takes 60 to 70 seconds to connect to CUCM (running 8.6.2) when it starts.
After Jabber registers with CUCM, there is no issue, it's just very slow to register.
Anybody getting the same behaviour? We have no such issue on previous versions of Jabber for Mac version 8 or Jabber for Windows version 9.
Thanks,
Fabrice

For those interested, I have the answer to my own question: if one of your configured DNS servers is not responding, Jabber 9.2.1 will delay registration to the phone services. This behaviour is seen only in this specifc version of Jabber, hopefully it will be fixed in the next release. Watch out if one of your DNS server goes offilne.

ATA-186 can be registered with CUCM v10.5

Hello guys ;
Please confirm me that ATA-186 can work with CUCM v10.5 ? .
Regards;
Shib

Loaded the latest firmware into CM, then manually on ATA firmware using this process as CM didn't change it:
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cata/186_188/3_0/english/administration/guide/sccp/sccp3_0/sccpaapc.html#wp1011450
I followed this link from another post regarding ASA not registering for an older issue.
http://www.cisco.com/en/US/docs/voice_ip_comm/cata/186_188/3_0/english/administration/guide/sccp/sccpaape.html#wpxref59054
Follow the part that mentions setting the SID0 & SID1 to "." no quotes. I did this and my ATA registered to CM. Screen caps attached.
I have a Cisco ATA 186 running on 10.5.1 and it shows to be registered. I can make calls on it. Not sure how it will do for faxes. HTH Please rate.

Percentage of Phones won't register after CUCM 9.1.2 Sub and TFTP failover

Hoping this has happened to someone else and they can shed some light on the subject. I have a CUCM 9.1.2 cluster running, pub, 2 subs, and 2 tftp servers. At the moment it's a small deployment so I have all phones registered to sub 01 as primary and using tftp01 as the primary tftp server. In order to have some VMWare maintenance done I recently shut down the pub, primary sub and primary tftp server forcing the phones to use the other half of the cluster. Everything there worked as expected, phones failed over, etc. The problem occurred after the VMWare maintenance was done. At that point I brought up the Pub and the primary sub (maintenance wasn't yet completed on the host that contained the primary tftp server). After the primary sub was up and back online is where the problem started. Random phones (all 8945 SIP that are all running the same firmware version SIP8941_8945.9-3-2-12) would just not register. Some of them would show registered in CUCM, however they were non-functional as DNs weren't displayed, no dial tone, etc. Others would just not register all together. In order to get a phone to register I had to perform a factory reset on the physical phone, if I did that they came back with no problem. Later after the maintenance was completed on the host that contained the primary tftp server and I brought that back online, I still had issues with phones however just a power cycle was enough to get those phones registered. I opened a TAC case one this but it ended up at packet captures and at that point ever phone I reset would just register correctly so I could never get an example of a phone that wouldn't register.
I'm convinced it's certificate related and having to do with the trust list, which is why I believe the factory reset on the phone would allow the phone to correctly register. There just doesn't seem to be any clear indication as to why it would be certificate related. Names weren't changed on any of the UC servers, VMWare version was upgraded from 5.0 to 5.1 but I can't see how that would have caused certificate issues.
Any help would be grateful or if this has also happened to anyone I'd love to hear what you did to resolve this as for future maintenance windows I have to be confident that phones will be able to fail over between cluster nodes.
Thank you,
Alex

So the phone is unable to authenticate the ITL it is getting or the new config file. This could mean that the ITL is corrupt on one of the nodes or that TVS isn't working properly.
I would try running "show itl" on each node and check the bottom of the output to see if the ITL is verified successfully.
I would also make sure TVS is running on all nodes okay.
You also should be able to just delete the ITL from the affected phones rather than doing a full factory reset in case this comes up again.

Remote app on iPad won't work with iTunes on iMac

I own two computers, a Late 2012 27inch iMac with i5, 16GB, Fusion drive and a 2014 MacBookPro Retina 13inch, both are running Yosemite, iTunes 12.0.1 and my iPad 4 is running iOS 8.0.2.
When I set up to control my iMac with wifi and my iPad 4, the remote software connects and I have the music library icon that shows up, but it doesn't actually run to control iTunes like it's supposed to do. When I use my MacBookPro, it works perfectly without any problem.
Any suggestions? I really want to use my iMac as my music server since it's a stationary system that placed next to my stereo system, but what should I try to make this work. I've used several different routers Apple and Non-Apple and the results are identical. The MacBookPro works great and the iMac doesn't. I've checked all of the settings and can't find anything different between the two computers.
Any help would be great.

OK.
As Demo indicated, IDs unfortunately can not be combined.
Decide which one you want to be "primary" and routinely remain logged on to that one on both the iPad and the computer. That way, all new purchases will be on the primary and you won't be making the problem any worse.
Change the password on one of the IDs so that both IDs use the same password.
The difficulty is in app updates. Both your iPad and iTunes on your computer will tell you that updates are available and it's possible to update them using either device (and a sync will update the other device). However, it's a nuisance updating from iTunes because you most log out and back in again, get the update, and when finished log out and back in again to get back on your primary.
Remember that the iPad is always logged in to the primary ID. When the iPad tells you that updates are available, you either "select all" or choose one at a time for updating. If you "select all," only those associated with the primary ID will be updated but sometimes you're lucky and that's everything. The apps on the secondary ID will not have been updated and they should subsequently be selected one at a time for updating. You will NOT need to log out and back in again! All that will be necessary is to enter the password.
If any of the above did not make sense, post back and I'll explain.

7941g's wont register with cucm 5.13

I have older 7940g's which register and pull down configs fine. The 7941g's will not. Im at a total loss.

The IT guy gave me the wrong phone information. They didnt have a g model they just had a 7941. Auto registration was not on either. I turned on auto register and deleted the 7141g's and everything came up fine. I work remotely and I rely on people to give me the correct information :)

CSF Device not registering with CUCM 10.x

Hello all

What will happen if Conference Bridge (CFB) is not registered with Call Manger?

I have a MRG consists of two CFB, it is found one is registered with CCM, the other is not. some users complain that the ad-hoc conference soft button is not working. So is that due one of the CFB is not registered? (I know all same type of resource within a MRG will be round-robin balanced).
will happen Call Manager allocate an unregistered CFB?

It will not allocate the unregistered one. Media Resource Manager will look for the available resources registered with CUCM according to the configuration and allocate the one thats available.

Unity Express 8.6.7 intgration with CUCM 10?

I'm working on a 2911, with a ISM-SRE-300-K9 running CUE 8.6.7 (confirmed clean install). The CTI Ports are not registering with CUCM, all the steps have been triple checked, yet they don't register.
The CUE talks to CM fine and pulls the 4 CTI Ports we configured on CUCM, but if you click the 'show available ports in CUCM" it immediately crashes the CUE and it reboots.
I have a case open and it may be a bug, but wanted to see if anyone here has CUE working with CUCM 10.
Thanks-

Yes, confirmed that is all correct.
The ports don't register and when you click "expand to also show available ports on cucm" the CUE crashes:
CRASH appsServices startup startup.sh System has crashed. The trace buffer information is stored in the file "atrace_save.log". You can upload the file using "copy log" command
if I enable jtapi debugs, it just says out of service:

Spa942 with CUCM 6.0

hello,
I have a spa942 phone and does not register with CUCM 6.0.Any idea on how to go about it.thanks.

You may need a Cisco SIP license. I know the SPA942 will work with Cisco's UC520 platform, but I thought on Callmanager you needed a SIP license in order to register a phone.

I have Polycom IP5000 phones running UC software 4.1.1 which do not stay registered with CUCM 9.1 for more than couple of seconds, I created digest user with username matching the DN of the phone, the phone registers for few seconds but then unregisters and stays unregistered for long period of time. Does anyone have a good guide or tips on how to make these phones work?
Polycom logs are not very helpful as all I see is this:

it looks like you do not have configuration file for this phone
check is it in default device profiles?
