Description

If two 'm=' lines are received in the SDP offer, the
device prefers the SAVP (secure audio video
profile), regardless of the order in the SDP.
Notes:

This parameter is applicable only when the
EnableMediaSecurity parameter is set to 1.

The corresponding global parameter is
MediaSecurityBehaviour.
Defines the maximum number of concurrent calls
(incoming and outgoing). If the number of concurrent calls
reaches this limit, the device rejects any new incoming
and outgoing calls belonging to this IP Profile.
This parameter can also be set to the following:

[-1] = (Default) No limitation on calls.

[0] = All calls are rejected.
Note: For Gateway IP-to-IP calls, you can configure the
device to route calls to an alternative IP Group when this
maximum number of concurrent calls is reached. To do
so, you need to add an alternative routing rule in the
Outbound IP Routing table that reroutes the call to an
alternative IP Group. You also need to add a rule to the
Reason for Alternative Routing table to initiate an
alternative rule for Tel-to-IP calls using cause 805.
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.
Notes:

When out-of-band DTMF transfer is used ([1], [2], [3],
or [5]), the DTMFTransportType parameter is
automatically set to 0 (DTMF digits are removed from
the RTP stream).
