<p class=MsoNormal> We’re running Asterisk 1.6.1.17 for our campus
voicemail server and Juniper M120s as our SBC. 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. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> We’re uncertain why this is happening and this is
where we are hoping you can help. In our environment the caller is any set on
the PSTN. They call one of our IP phones which no one answers. 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.<o:p></o:p></p>
