Route ISDN Voice calls over LAN/WAN

Is it possible within the relms of normal Cisco LAN to have an ISDN Line coming into one building, Connect it to a LAN/WAN so we could pick up the voice calls on the ISDN on the other end, In a different location?

There are no CCM logs to tell you that, CUCM has nothing to do with the RTP, this is usually QoS issues, you always hear "nothing has changed" but they often overlook things they think are not worth mentioning, or that they think would have nothing to do. Make sure really nothing has changed.
The only way to look at this would be to run a sniffer trace on both ends to see what you send, and you receive.

Cross connected calls over MPLS WAN

Hi,
I have an issue with one of my offices that has me extremely puzzled.
When users call users in other offices, sometimes the calls get cross-connected, where they are suddenly talking to another caller.
Our telephony provider is insisting it is my network, but I have this office router and switches configured the same as our other 5 offices that don't have this issue.
They are now trying to say it is an MPLS issue from our Telco, but I figure I would be seeing issues with data going over that link as well.
Has anyone ever experience this "crosstalk" before?
The routers at the offices are 2811/2851, with 10meg MPLS WAN between, and 3560/3750 PoE switches for the phones.
Any advice or tips would be greatly appreciated!

The 2851 at our head office is running 12.3(8)T8.
The 2821 at the remote office is running 12.3(8)T8 as well.
We are not using CCM, we are using a Mitel VoIP solution (which I hate and wanted to go with Cisco instead!), which is using Minet (shows as RTP traffic).

Looking for help to improve Airport performance over LAN (WAN is fine)

Ok, I've read through several threads on this forum that address problems people are having with slow performance with Airport. I've also checked out all of the Apple KBs that address Airport, recommended settings. Unfortunately my issue isn't addressed by anything I've read to date.
The bottom line is that both download and upload performance between any of my devices and the internet is fine, no problems. I am paying for 30MBps download from Verizon FIOS, I routinely get 20, and I'm guessing that the delta is Verizon's problem, not my network's. However, streaming from my media server to another device on the wireless LAN is a different story entirely. I get somewhere between 1 and 2 MBps, tops, and this poses big problems for streaming music and movies.
My network is comprised of 3 Airport Expresses. One of them is a MC414LL/A model. This one is connected to my Verizon FIOS Actiontec MI424WR router (which I have set to bridge-mode according to the instructions provided at http://www.dslreports.com/forum/r17679150-Howto-make-ActionTec-MI424WR-a-network -bridge) via CAT5 ethernet. This Airport Express is set to "create a network" network mode, "802.11 only (5GHz) - 802.11b/g/n" radio mode (although I have also tried "802.11 only (5GHz) - 802.11/n only (2.4 GHz)" radio mode, and this didn't solve the problem). Finally, I have chosen 2.4 and 5GHz channels that have little interference (2 and 161 respectively). My other two Airport Expresses are MB321LL/A models and are set to "Extend a wireless network" network mode, with the 5GHz network chosen as the network that they extend. (I have tried switching over to having them extend the 2.4GHz network, and performance gets worse, not better.)
I am using a late 2009 Mac Mini as a media server. It is connected to the 5GHz network (though I've tried the 2.4GHz network), and it runs XBMC and JRiver media servers (not simultaneously, either one or the other.) I have a PS3 and a Sony Blu Ray player, each plugged into one of the MB321LL/A Airport Expresses via CAT5 ethernet, and I stream media to each of these devices via one or the other media server (both devices are DNLA-enabled). My Mac Mini has a 3TB external hard drive connected via FireWire 800, which is where all of my media resides. In addition to streaming media over the network, I have a TV plugged directly into the Mac Mini. When I play media to this TV, performance is outstanding, so I'm confident my poor performance to the PS3 and Sony BDP is a network issue, not an issue with the external drive.
Although my building has several other wireless networks, only one of them is 5 GHz, and it isn't using channel 161. The 2.4 GHz band is crowded with several networks, although channel 2 is usually in the clear. I have tried switching let Airport choose a channel automatically, and I haven't noticed a difference. It has occurred to me that the problem could be with how I bridged the Verizon Actiontec router and not with any of the Airports, but I don't get any errors (e.g. double NAT errors, which some people who have bridged improperly get), and I am pleased with my download and upload speeds to the internet. The issue is only on my LAN. Finally, yes, all of my firmware is up to date, version 7.6.3 on all three Airport Expresses.
Can anyone offer me suggestions for how I can get better performance streaming media from my server to the two playback devices? Since all 3 Airport Expresses support 5GHz, I'd have thought I'd be able to take advantage of 802.11n speeds when streaming between them. (MB321LL/A supports "Draft N", but does this matter?) With the settings that I'm currently using, I can't stream faster than 2MBps (and that's on a good day), which is below what I ought to be able to get rom 802.11g. This is especially problematic when I try to stream hi res (96 MHz / 24 bit or higher) music files, whether uncompressed or compressed. I hear awful pulsing sounds through my speakers. If I pause the track and let my streaming device buffer, I might get 10 or 15 seconds of clean playback, but then it starts the pulsing again as soon as the buffered music is finished playing. On occasion when I stream music from my iPhone via Airplay to one of the Airport Expresses, I get clean playback most of the time, but on occasion the music cuts out. (It's my understanding the Airplay requires ~800 Kbps, which seems consistent with my LAN speed usually being between 1 and 2 Mbps but sometimes dropping).
I have iStubler and I've used the Apple network diagnostics -- these are the tools that led me to choose channels 2 and 161 for 2.4 and 5GHz respectively. I'm sure I could be using these tools to learn more about my network's performance, but I'm sure what to look for.
Thanks for your suggestions.

Ok, cool. I'm really glad that the issue has been isolated. Thanks a ton for your insight!
Hopefully I can find a spot where the signal strength of the hub is noticably better but that isn't too inconvenient for an ethernet run. My Sony BDP, which is the device connected to the problem basestation, has wifi capability, so I could always ditch the ethernet cable if the best spot for the basestation doesn't permit a cable run. But I'm aware that ethernet usually offers faster transfer speeds than wifi. Moreover, I'm not sure that the Sony BDP supports 5GHz. It might be a 2.4GHz-only device, in which case I'll have new interference issues to contend with, since like I said in my original post, there are several other 2.4GHz networks in my building.
Anyhow, now that I understand the problem, I can figure out a solution. Thanks again.

Voice/video calling over BBM is no longer available for OS 10.3.1.1565

After updating to OS 10.3.1.1565 for my BB Passport voice/video calling over BBM is no
longer available. I CANNOT MAKE VOICE OR VIDEO CALLS OVER BBM neither I CAN RECEIVE CALLS
OVER BBM. I do use voice calling over bbm on a daily basis and I feel like I am now without
my phone!
I did update ALL the application offered for the update. Right now there are NO applications
available for the update - all are up-to-date.
BB World indicates I use BBM 10.6.4.10. I did REFRESH BB World with no changes. Yet NO UPDATES
are offered.
When I select the BBM application in BB World among the list of Installed application it
says in red color "Unavailable for this device".
I see some use BBM 10.6.5.10. Are there troubles with voice/video calling over BBM for
10.6.5.10 & OS 10.3.1.1565?
Maybe the bug is with BB World that is to be updated itself? But it does not offer me to
update one.
Does anyone have an idea how to fix that?
Thanks!
Solved!
Go to Solution.

I wish I new how to update
I have purchased yesterday BB Classic for my wife and also updated OS for it.
BBM works flawlessly with OS 10.3.1.1565 and preinstalled BBM 10.5.15.19. However its also indicates in red that the application is "Unavailable for this device".
Anyone from Blackberry, would you please suggest how to update BBM in my case?! It is that vital for me.
Thanks.

Setting up a Voice call from ONT/OLT to Softswitch via SBC

Hi,
I am setting up a voice call over SBC to softswitch basically SIP over ISUP,now i have a small issue that my SIP user is getting registerd at both SBC and Softswitch and able make OG/IC calls.
Now my question is whether will i be able to ping the client ip from SBC,since i am not able ping the client ip.is there any firewall restriction at OLT/ONT side.

Hi HW,
The PBX is a Panasonic TA308. There is no special interface to the PBX, the line port on the SPA3102 is simply plugged into an extension, like another phone. Anyone calling that extension will have the call routed through the SPA & PAP2 to the remote phone.
The whole setup is totally seamless, & transparent to the user. As we are on a local network there is virtually no latency. There is a slight tendancy to echo, but the echo suppression mostly takes care of that.
THis has been a good exercise, and once I got my head around what I was trying to do, with your help, it was pretty easy. I think the hook flash timing would be the thing which gives most users a problem, as it seems to vary widely around the world. I was surprised at the difference between the US and NZ (.1 & .9 to .07 & .13). There didn't seem to be any other critical differences.
Now I am the local expert on VoIP "In the Kingdom of the blind, the one-eyed man is King."

Calling over WiFi

Do BT antcipate any introduction of a "calling over WiFi" app?
EE are introducing a seamless approach in very selected phones running EE firmware only. However I prefer Three's app approach and being able to select which AP is authorised for WiFi calling and works pretty well. Never got on with O2's TuGo!

The free Zoiper app is pretty useful. It's a VOIP client that runs in the background on your cellphone. It connects VOIP calls over whatever physical network is available at the time. Whether GPRS, UMTS, HSPA, LTE, or 802.11, including BTWiFi hotspots.
Direct Inward Dialling (DID) telephone numbers for VOIP are also available for free from certain VOIP providers. The Zoiper app is then configured to accept inbound calls to those DID numbers. The Zoiper client can actually handle multiple SIP accounts. Useful if you're abroad, for avoiding roaming charges, and for making low-cost domestic or international calls (i.e. least-cost-routing).
By shopping around for VOIP providers, making calls to geographical numbers in the UK, USA, and many other countries can be virtually free, as well as free to US mobiles. Those calls that are still charged, are generally minimal in cost.
With the maturity of packet-switched VOIP calling -- and the availability of multiple physical networks to carry the underlying connection -- making a voice-call over the traditional cellphone has surely had its day.

External and internal mikes are not automatically switching over either recording or on voice calls

My laptop model name is HP Pavilion dv4-1100ea which is shipped with Vista Home premium 32 bits and has got service pack 1.
Restored the laptop to factory setting since then I am having the following problems; I had the same problem when my laptop was brand new and whenever I reset the laptop to factory setting I get the following problems:
1. External and internal mikes are not automatically switching over either in middle of the recording using sound recorder or while the call in progress on voice calls (skype):
   Using the sound recorder if I start recording the sound with external mike and in-between recording if I switchover from external mike to inbuilt mike and later on when I play back I can only hear the sound up till where I used the external mike during recording, after the switchover to inbuilt mike I cant hear any sound.
   But if I start the recording with inbuilt mike and in between recording if I plug in the external mike and later on when I play back I can only hear the sound up till where I used the inbuilt mike during recording , after the switchover to external mike I cant hear any sound.
   So in brief both my external and internal mikes are working fine, only problem is that if I start recording (using sound recorder) or voice call with one specific mike, I have to continue with it till the end. I can’t switchover to another mike in between the conversation (voice call) or recording, if I do so, I have to select the mike manually in chat software but while recording I cant even select manually because in laptop, it takes the mike whichever is in current use as default mike in recording tab(sound window). The green tick automatically (in recording device tab) switches over according to the use of mike. Though the green tick in the recording tab is switching over automatically according to use of mikes, its not picking up the sound after switch over during recording.
2. And also when I click on recording device tab in sound window and plug in external mike, though the green tick automatically switchovers from internal to external mike, while I speak both internal and external mikes volume meter respond to the sound inputs by rising and falling but if I take out external mike, green tick goes to internal mike and when I speak only internal mike volume meter respond to sound rising up and down not the external mike.
To resolve the issue I have tried following steps with no luck:
1.I have checked the mikes(internal and external) properties, the both mike shows to be enabled in general tab, in level tab the volume is set to 100 and in advanced tab , all options are selected.
2. In device manager I have got only one audio driver named as “IDT High definition Audio CODEC”. I have uninstalled the audio driver and reinstalled it using scan for hardware option
3. Uninstalled the audio driver in device manager and reinstalled the audio driver using recovery manager > advanced option> hardware driver re-installation.
3. I have updated the BIOS(Insyde F.65, 12/02/2010).
4. I tried to update the audio driver using below link but things went more worse so I did system restore (not factory setting though).

Sounds like you need to upgrade to the iPhone 5s
The 5s has Touch ID
You can unlock your phone with your finger instead of typing in a key code
No swiping to unlock either, just touch the home button
You can enrol multiple fingers as well
Here is a video of it in action
http://www.apple.com/iphone-5s/videos/#video-touch
Or wait and see what iPhone 6 has to offer
That being said, as desiel vdub posted if the phone is up to your face, the proximity sensor should turn the screen off
And when you lower the phone turn it back on again
Not sure about the phone locking when your on a call doesn't sound right

Sending Data Over Voice Call

helo guys can one one help me im final year student, im planning to develop an application in which user can send data over voice call... is it possible?? if yes then please guide me

No, that is not possible. You can't do voice stuff with j2me/midp.

Whenever I call people over a voice call , they can't hear me speak .. but whenever I use facetime/facetime call they can hear me on speaker , hearphones

whenever I call people over a voice call , they can't hear me speak , I can hear them speak though ! I've tried earphones and speakerphone .. but whenever I use facetime/facetime call they can hear me on speaker and hearphones

Audio over LAN

Hi
I am using Logic on a Quad core mac and running Vienna instruments as 4 Vienna Ensembles routing the audio back into Logic with soundflower. However I am trying to take some of the load of my DAW machine and so have ordered a 2 Mac mini's to put the vienna ensembles on. I am going to use Midi over LAN to send the midi, but was wandering if there is anyway to get the audio back over lan without me having to purchase audio interfaces for each mini and the mac pro?
Has anybody tried using apples AUNetSend and AUNetReceive? Did these work fine or are there problems?
Another solution I have been looking at is wormhole? Has anybody got this working fine with logic and two mac's?
Any advice would be great!!!
Thanks,
Simon

No, I have not tried them.
I am trialing MusicLab's Midi Over Lan product to use the XP PC in my basement to serve up midi to my Mac. Also on trial is a VST called wormhole to pipe audio upstairs too.
So far, so good, though I haven't tried going the other way, mac to pc.
