<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>
