Hello *,
Thanks for the information.
I have some more queries,
1)When INVITE send from UAC with the session-expires value
less than the
Min-SE configured in the proxy, the proxy will reject the
INVITE with 422
response and include the Min-SE header.After that UAC will
send a new INVITE
with session-expires and Min-SE returned in the 422
response.
Now when RE-INVITE send with session-expires less than
Min-SE then what will
be the behaivour of the proxy?Again 422 will be send by
proxy?
2)what is the real use behind the 422 response?
when INVITE is received with session-expires less than the
min-se configured
in proxy then the proxy can modify the session-expires to
the min-se
configured value and forward the INVITE to terminating side
and in the 200
OK response the UAC will be indicated with the new
session-expires and if
parameter refresher=uac, then uac can refresh the session
considering the
new session-expires.Whether this is possible?
If this is applicable a INVITE may not rejected.
Pls give your points.
Best Regards,
Venkatesh
