All,

    Should Expires header be startd for re-Invite?

    Expires header in initial INVItE helps to avoid the race condition of 
infinite waiting since transaction
stops timer B, on receiving the first 1xx. The same can happen for reINVITE 
also.

    If Expires can be started, should CANCEL be sent for reINVITE when it 
fires?

Thanks in adv,

Best Regards,
Mohammed Hanifa
