[OpenSIPS-Users] Dialog timeout_avp kills call

[Duane Larson]

Hey Anca.  Yeah it does kind of sound like a stupid question.  I guess I was
trying to resolve this issue (*dialogs* in the invalid "CONFIRMED NO ACK"
state)
http://opensips-open-sip-server.1449251.n2.nabble.com/Killing-confirmed-no-ack-dialogs-td6223926.html

The timeout_avp during the initial INVITE and then during the ACK does solve
this issue, but I was thinking that the SIP clients might send a REINVITE or
an UPDATE every X minutes to reaffirm that the call is still up or good.  I
am pretty sure from my testing that the Snom phones do send REINVITES and I
think the Cisco phones send UPDATES.  It looks like the Counterpath Bria
client and Blink don't do anything like this.  But now that I really think
about it I guess I could just raise the timeout value to something larger
than 2 hours like 5 hours or 8 hours.  I guess there aren't that many types
of phone calls that should last 5 to 8 hours.  The main thing I wanted was
the 120 second timeout in case there wasn't an ACK.

Thanks for answering back to my stupid question.
