| Description | This object reflects the initial value for the retransmit timer
for final responses to INVITE requests. If timer G fires, the
response is passed to the transport layer again for
retransmission, and timer G is set to fire in MIN(2*T1, T2)
seconds. From then on, when timer G fires, the response is
passed to the transport again for transmission, and timer G is
reset with a value that doubles, unless that value exceeds T2,
in which case, it is reset with the value of T2. The default
value MUST be T1 for UDP transport, and its value MUST be 0 for
reliable transport like TCP/SCTP. |
