Hello everyone, first time here, need a little help.
I'm having some trouble to find a solution to the following problem.
Recently I've installed CME 9.1 using the router 2921. Most of the phones are SIPs, model 3905 (around 20 of them), with the last firmware updated.
Some users are complaining one way audio issue in internal calls, from a extension to another (only in sip phones)
With Wireshark capture I could see that RTP packets are being sent and receive by the router and not directly trough the phones. Is this normal in CME? When a call with problems occours (one way audio) there is no audio in one way, but router still sends confort noise packets.
Here is my config.
Thanks for any help.

You may want to save yourself further time and go straight to the TAC with this.
The 3905 phones have already a poor reputation, if there is someone that has to get them working, that is Cisco, not the partner (or integrator).
By the way, media should not go to router in first place.

Looks like 3905 has some problems indeed..
Cisco TAC has provide a new firmware to SIP 3905 (3905.9-2-2ES2) that in my case solved the problem. Unfortunelly the firmware is not available to direct download.
Thanks to everyone.
ā02-08-2013 03:13 AM
you need probably to do
voice service voip
sip
bind control source-interface GigabitEthernet0/0.220
bind media source-interface GigabitEthernet0/0.220
how many SIP phones possible ?
voice register global
max-dn ?
max-pool ?
and how many phones possible under
telephony-service
max-ephones ?
ā02-08-2013 05:26 AM
Hi there, thanks for replys.
We are about to open a TAC to Cisco, but still trying to figure this out...
I'll try the bind command in sip and check the results.
telephony-service
max-ephones 5
max-dn 5 no-reg both
voice register global
.
max-dn 60
max-pool 70

I had a similar problem and I upgrade firmware on CP3905.9-2-2-0
But the problem remains external call.

You need to open a TAC case to get the firmware...Its not available for download

Hi ,

Thanks

Hi Purna!
Could you, please, send me (dsoloviov@gmail.com) that great firmware for 3905?
ā10-31-2013 09:48 AM
Hello Dmytro
Cisco has a new firnware available at the download page. I believe this firmware has already the necessary correction for this problem.
You may download direct from cisco.com/download, look for the firmware cmterm-3905.9-4-1-0.cop.sgn.

Hi Martin,
I'll try the official firmware version 3905.9-4-1-0 next week. But I don't see any resolved caveat regarding one-way audio in the release notes... We'll see.
Nevertheless, thanks for recommendation.
Dmytro
ā11-01-2013 02:48 AM
Ooops... I've missed some resolved caveats in the release notes:
CSCtw59242 Calls established with no audio on IP Phones 3905
CSCuc17539 3905 Phone - No audio
I think I should try 3905.9-4-1-0 ASAP
Thank you guys!
ā03-13-2013 05:20 AM
In the phone config you could insert the command "no vad" (if not yet set) in voice register pool, this doesn't help me to solved the problem, but it was a indication from Cisco TAC.
Only after firmware upgrade the issue was solved.
Godd luck at your task and let us know if it helped.
