Description
■ [2] Before Manipulation = Copies the called number
before manipulation. The device first copies the original
called number to the SIP Diversion header, and then
performs IP-to-Tel destination phone number
manipulation. Thus, the called (i.e., SIP To header) and
redirect (i.e., SIP Diversion header) numbers are
different.
Note: The corresponding global parameter is
CopyDest2RedirectNumber.
Defines the maximum number of concurrent calls
(incoming and outgoing) for the SIP entity associated with
the IP Profile. If the number of concurrent calls reaches this
limit, the device rejects any new incoming and outgoing
calls belonging to this IP Profile.
The parameter can also be set to the following:
■ [-1] -1 = (Default) No limitation on calls.
■ [0] 0 = All calls are rejected.
Enables DTMF signaling.
■ [0] Disable (default)
■ [1] Enable
Defines the first preferred transmit DTMF negotiation
method.
■ [0] Not Supported = No negotiation - DTMF digits are
sent according to the parameters DTMFTransportType
and RFC2833PayloadType (for transmit and receive).
■ [1] INFO (Nortel) = Sends DTMF digits according to
IETF Internet-Draft draft-choudhuri-sip-info-digit-00.
■ [2] NOTIFY = Sends DTMF digits according to IETF
Internet-Draft draft-mahy-sipping-signaled-digits-01.
■ [3] INFO (Cisco) = Sends DTMF digits according to
the Cisco format.
■ [4] RFC 2833 = (Default) The device:
✔
negotiates RFC 2833 payload type using local and
remote SDPs.
✔
sends DTMF packets using RFC 2833 payload
type according to the payload type in the received
SDP.
✔
expects to receive RFC 2833 packets with the
same payload type as configured by the parameter
RFC2833PayloadType.
✔
removes DTMF digits in transparent mode (as part
of the voice stream).
■ [5] INFO (Korea) = Sends DTMF digits according to
the Korea Telecom format.
