[asterisk-users] Asterisk 1.6.1.17 ACK/BYE question

[Trevor Benson]

We have a box running 1.6.2.11 on CentOS 5 using the RPM's from the Digium CentOS repository.  We just left a 60 second voicemail on the system and had the full audio as well in the inbox.  Not sure how your SIP configuration ties your SBC in, but native "users" created via users.conf and sip.conf appears to be working for me.  Wouldnt be able to test more without knowing what settings you had between Asterisk and the SBC.

The user hears the recording being played, begins to leave a message and is disconnected about 10 seconds into the call.

Unanswered calls, which arrive via the SBC, are diverted to voicemail using a 302 redirect when the called party doesn’t answer. In this case the caller is able to hear the greetings and begin to leave a message only to have Asterisk terminate the call mid-recording.

Our proxy, SER, responds to the SBC with a 302 redirect and the call is diverted to Asterisk. The caller hears the unavailable greeting for 6-4050, begins to leave a message and is cut-off after about 10 seconds. In an ngrep trace we see Asterisk receive an ACK from the SBC and it immediately responds with a BYE message for that call.
