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

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?
I think you may be misunderstanding this a bit. 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.
Thanks. My issue is a SIP issue.
