I've an issue using a 3845 router as a voice gateway.
Internal voip calls are placed through a call manager 6 and external calls go through an E1 PRI interface.
Users claim that after ten seconds of two-way audio conversation the call is automatically dropped. After some debug I discovered the router is sending the ISDN DISCONNECT message after 10secs not the PSTN.
I attached a show run and a debug isqnd q931 of a dropped call. Calling numìber is 00000 called is 46299.
Llet me know if you need more shows or debug.
thanks and regards
Modified by lorenz84gDD The issue is mainly on incoming calls from the pstn. And I get the release cause: *Feb 16 11:02:52.342: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x9DBB Cause i = 0x80AF - Resource unavailable, unspecified
