Summary:                    Timer support
Description: 
When acting as uac the 200ok replay to uas does not include the sessoin
expiry and refresher timer. This turns the timer off.

RFC4028, chapter 7.2:
   "If the 2xx response did not contain a Session-Expires header field,
   there is no session expiration.  In this case, no refreshes need to
   be sent.  A 2xx without a Session-Expires can come for both initial
   and subsequent session refresh requests.  This means that the session
   timer can be 'turned-off' in mid dialog by receiving a response
   without a Session-Expires header field.

I think it would be useful to have some logging of this happening between
Asterisk and the client showing it clearly. Please provide SIP debug traces
along with SIP history as enabled in sip.conf.

You can log this to a separate file using logger.conf and then attach the
resulting log to this issue. Thanks!
