Summary:                    Missing session-expires from Asterisk to the phone.
Asterisk not working according to RFC
Description: 
There is no Session-Expires header present in the 200OK response sent by
asterisk to the ReINVITE/SessionRefresh from the phone.            
Because of this the SessionRefresh is considered as failed as marked
within the Warning header in the ACK request.

According to RFC4028 (chap.9 UAS behavior ):
"If the UAS wishes to accept the request, it copies the value of the
Session-Expires header field from the request into the 2xx response.
and
The UAS MUST set the value of the refresher parameter in the
Session-Expires header field in the 2xx response."




Precondition:
--------------
Asterisk configuartion :sip.conf:

session-timers=accept (Asterisk default)
session-expires=3600
session-minse=90 (Asterisk default)
session-refresher=uac 

Scenario:
==========
760: IP-Addr = 192.168.4.163, SIP-Session-Timer=true,
SIP-Session-Duration: 120 sec
761: IP-Addr = 192.168.4.198, SIP-Session-Timer=true,
SIP-Session-Duration: 150 sec

760 calls 761 which accepts the call.
>>>ERROR<<<:Connection is broken after 60 sec.

Phone type used:
Both 760 and 761 are OpenStage 40.
