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

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

Hi Mark,

I used the ipip-gw as an sbc and all device interfaces involved are using
public addresses.
The only voip to voip connection here is between the ccm, ipip-gw and
as5400.

Do you have a recommendation on how I should configure the callmanager,
ipip-gw or as5400?

Thanks,
Ryan
