Happy holidays! I am playing with SST module for session timer and have some
questions that I would like someone can help me out. 1. First question is the
422 message is not sent immediately after receiving INVITE with SE header
smaller than default 1800 sec. My OpenSER script is very strait forward as the
example in the module document: if (method=="INVITE") { if (sstCheckMin("1"))
{ blah blah.... exit; }}Debug
on OpenSER shows the result returns -1 when an INVITE contains SE and Min-SE
timer at 90. It is until the INVITE hits lookup("location") it replies a 422.
2. Right after OpenSER sends a 422 it proxies the INVITE to the called party at
that same time. So the call flow looks like: Caller
OpenSER Callee INVITE (SE 90)=======> <======= 422 ====
======INVITE===> === INVITE (SE 1800)==>
3. The 422 Session Timer Too Small message put MIN-SE and Server headers in one
line which looks like: MIN-SE: 1800Server: OpenSER........... Has anyone tried
SST module before and how did it work for you? Many thanks for you help. Best
regards,Patrick
