Example:
The user registers a SIP account for the IP phone and then set the value of Timer T1,
Timer T2 respectively (Timer T1: 0.5, Timer T2: 4). The SIP registration request message
will be re-transmitted between the IP phone and SIP server. The re-transmitting and
doubling of Timer T1 (0.5) will continue until the retransmitting time reaches the Timer T2
(4). The total registration request retry time will be less than 64 times of T1 (64 * 0.5 = 32).
The re-transmitting interval in sequence is: 0.5s, 1s, 2s, 4s, 4s, 4s, 4s, 4s, 4s and 4s.
Timer T4

client and server.
