Hi,
I am experiencing a weird thing. In calls that are received from the PSTN into a NEC NEAX 2400 PBX that are inmmediately forwarded to a Cisco IP Phone on a Callmanager 4.1 cluster, the call is succesfully established, and both parties can talk, but after 20-120 seconds the audio is lost. (The Call remains stablished, packet count in the call statistics keeps increasing, for both Tx and Rx values and yet , audio in both ways is lost.) Call remains stablished until the parties hung up the speaker.
Has anyone experienced something like this?
All debugs of ISDN q931 come clean, with all the calls completing the full process and ending in Normal Call Clearing

If you have configured the gateway as h.323 you neeed to bind the interface using the command h3230-gateway voip bind srcadd

It is not the case, as it is configured already. Even if it is so, it does not explain why the audio starts and then gets lost!
