Audio lost after 20-120 seconds on call forwarded from PBX to Callmanager
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?
