All,
I have a query in the below scenario, Considering UAC is configured
with T1 =500ms and T2=4s.
UAC sends BYE to SIP Server and SIP Server responds with 100 Trying
only.
In this case when UAC is supposed to retransmit the BYE ?
Is it at T1 or T2 interval ?
Below two sections indicates different behaviour .can any one clarify ?
As per RFC 3261
17.1.2.1 Says
"If a provisional response is received, retransmissions
continue for unreliable transports, but at an interval of T2 "
17.1.2.2 " If Timer E fires while in the "Proceeding" state, the
request MUST be
passed to the transport layer for retransmission, and Timer E MUST be
reset with a value of T2 seconds." { Timer
E will be set to T1 }
Regards,
-Sathish
