Subject: [SIP] Detection of UAC failure

Hi,

In the initial INVITE, how an UAS can know that the UAC is still alive?

The UAC can do this by retransmitting the INVITE periodically or by
bounding the duration of the INVITE with a Expires header, but how an
UAS can be sure that the UAC is alive (if the UAS send the 200 OK after
a very very long time), if the PRACK extension is not supported and the
UAC do not add an Expires header?

Thank you for your help,
