session -exp
Hi,
what is the use of "Session-Expires" header in sip message.
Ua is sending invite to Media server ans MS is responding with 200OK. Ua sends
back with ACK. And then MS is sending Re-Invite with Session-Expires: 30.
SDP is same in 200OK and Re-Invite.
[Nataraju] Better
you take a look at the session timer draft: draft-ietf-sip-session-timer-12.txt.
The session
timer is of more useful to Proxies than UA. The basic necessity for this mechanism
to guard the session for a predefined amount of time. Instead of keeping the session
for ever in proxies even if UAC or UAS gone down with informing the other
entities…
Regards,
Vivek
