from SIP 401/403/404/407 Via header "received"/"rport" parameters in REGISTER

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 HT813 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 0
DTMF Payload
Type
Defines payload type for DTMF using RFC2833.
Preferred DTMF
method (in order)
Sorts DTMF methods (in-audio, via RTP (RFC2833) or via SIP INFO) by priority.
Disable DTMF
Negotiation

Default is
No
