Defines T1 timeout value. It is an estimate of the round-trip time between the
client and server transactions. For example, the HT812/HT814 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.
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.
Configure the SIP Timer D defined in RFC3261. 0 - 64 seconds. Default is 0.
Defines payload type for DTMF using RFC2833.
Sorts DTMF methods (in-audio, via RTP (RFC2833) or via SIP INFO) by
priority.
Uses above DTMF order without negotiation.
Default is No.
When enabled the RFC2833 events are generated until key is released.
Default is No.
Default is No. If set to yes, flash will be sent as DTMF event.
Overrides the default settings for call control when both channels are in use
Enables do not disturb, call forward and other call features via the local
feature codes on the base. Otherwise, ITSP feature codes can be used.
Default is Yes.
Configures a user ID or extension number that is automatically dialed when
off-hook. Only the user part of a SIP address needs to be entered. The
HT812/HT814 will automatically append the "@" and the host portion of the
corresponding SIP address.
Specifies the auto-dial delay after off hook.
