SIP T1 Timeout Defines T1 timeout value. It is an estimate of the round-trip time between the client and
server transactions. For example, the HT801 will attempt to send a request to a SIP
server. The time it takes between sending out the request to the point of getting a
response is the SIP T1 timer. If no response is received the timeout is increased to
(2*T1) and then (4*T1). Request re-transmit retries would continue until a maximum
amount of time defined by T2. Default is
0.5 seconds.
