SIP T1 Timeout is an estimate of the round-trip time of transactions between
a client and server. If no response is received the timeout is increased and
request re-transmit retries would continue until a maximum amount of time
define by T2. The default setting is 0.5 seconds.
SIP T2 Timeout is the maximum retransmit time of any SIP request
messages (excluding the INVITE message). The re-transmitting and
doubling of T1 continues until it reaches the T2 value. Default is 4 seconds.
