[cisco-voip] Callmanager 3.3 to 7206 IPIP-GW

[Mark Holloway]

One way audio is usually a NAT problem. Does the issue happen with VoIP to
VoIP calls or just VoIP to PSTN?

Hi All,

 

 

I'm currently working on a callmanager 3.3 to place calls through a 7206
IPIP-GW.

Here is my current setup:

 

(Caller) IP Phone -> CCM -> IPIPGW -> AS5400 -> TDM -> Phone (Receiver)

 

My problem is that the audio is only one-way, no audio on the caller's end;
the receiver

can hear the caller.

 

I've set the IPIP-GW as an inter-cluster trunk on the CCM and had the MTP
enabled and

disabled, but I still get the same result.  I've also set an incoming
dial-peer and outgoing

dial-peer on the IPIP-GW and forced a G711u codec.

 

One bahavior I have observed is that I hear the receiver's audio for a short
period and then

it goes silent. Connections seem normal via show command:

 

Total call-legs: 2
    493893 ANS     T9     g711ulaw    VOIP        P2131234567
202.XXX.XXX.118:18844
    493894 ORG     T9     g711ulaw    VOIP        P12134300001
65.XXX.XXX.12:22480
 

 

I'm Using IOS c7200-adventerprisek9-mz.124-9.T1.bin 

 

 

Any ideas anyone?

 

Thanks!

Ryan
