I have a case where a call from the PSTN to our SER proxy goes unanswered.
As a result it is relayed to our Asterisk server for voicemail. However
before
the greeting plays the caller hangs up. This results in an empty message
being created and emailed or the mwi gets activated.
I saw a few posts about Disconnect Supervision and Disconnect Supervision
with inbound SIP connections but I did not see any resolution to the SIP
question.
Does this sound like a SIP Disconnect Supervision issue? If not what seems
to be the issue? Also does anyone have any suggestions on how to stop
these messages from being created?
Thanks,Steve

Think you really want to read about in voicemail.conf: ; How many seconds of silence before we end the recording maxsilence=10 ; Silence threshold (what we consider silence, the lower, the more sensitive) silencethreshold=128 ------------------------> voicemail.conf > > ; Minimum length of a voicemail message in seconds for the message to be > ; kept The default is no minimum. > minmessage=3 > > Does it for all channels 8-) > > Brett > > On 11/3/2005, "Steve Blair" <blairs@isc.upenn.edu> wrote: > > > > I have a case where a call from the PSTN to our SER proxy goes unanswered. > >As a result it is relayed to our Asterisk server for voicemail.

Disconnect supervision is a PSTN issue not a SIP issue. Presumably your problem occurs because the caller hangs up and the telco doesn't signal this to you in a timely fashion. Therefore your device doesn't go on hook and it doesn't tear-down the SIP session.
