User's Manual 342 Document #: LTRT-10466
Mediant 500L MSBR
Parameter Description
[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.
Web: First Tx DTMF Option
CLI: first-tx-dtmf-option
[IpProfile_FirstTxDtmfOption]
Defines the first preferred transmit DTMF negotiation
method.
[0] Not Supported = No negotiation -
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).
If an ISDN phone user presses digits (e.g., for interactive
voice response / IVR applications such as retrieving voice
mail messages), ISDN Information messages received by
the device for each digit are sent in the voice channel to
the IP network as DTMF signals, according to the settings
of this parameter.
The corresponding global parameter is TxDTMFOption.
Web: Second Tx DTMF Option
CLI: second-tx-dtmf-option
[IpProfile_SecondTxDtmfOption]
Defines the second preferred transmit DTMF negotiation
method. For a description, see IpProfile_FirstTxDtmfOption
(above).
Note: The corresponding global parameter is
TxDTMFOption
Web: Rx DTMF Option
CLI: rx-dtmf-option
[IpProfile_RxDTMFOption]
Enables the device to declare the RFC 2833 'telephony-
event' parameter in the SDP.
[0] Not Supported
[3] Supported (default)
