• The admin password if no SIP account is configured on the HT.
• With the credentials of the SIP account if configured on the ATA.
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/HT802 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.
SIP T2 Interval
Identifies maximum retransmission interval for non-INVITE requests and
INVITE responses. Retransmitting and doubling of T1 continues until it
reaches T2 value. Default is 4 seconds.
SIP Timer D
Configure the SIP Timer D defined in RFC3261. 0 - 64 seconds.
Default is 0
