Hello, does anybody ever meet the following scenario:

=> Call get disconnected when both calling and called parties place the call in a mute state (for 2 minutes)

Calling phone is 7960 phone on CallManager 4.1(3) and called party is any phones on the PSTN. PSTN is connected with 2821 MGCP gateway.

In the deb isdn q931, we can see:

ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x888D

Cause i = 0x80A9 - Temporary failure

I am looking at a isdn timer problem or a call inactivity detection...

Any idea ?

Thanks a lot.
