Version 7.2 455 Mediant 1000B Gateway & E-SBC
User's Manual 20. Coders and Profiles
Parameter Description

[1] After Manipulation = Copies the called number after
manipulation. The device first performs IP-to-Tel destination
phone number manipulation, and only then copies the
manipulated called number to the redirect number sent in the
Q.931 Setup message to the Tel. Thus, the called and redirect
numbers are the same.
 [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.
Number of Calls Limit
call-limit
[IpProfile_CallLimit]
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] = (Default) No limitation on calls.
 [0] = All calls are rejected.
Gateway DTMF
Is DTMF Used
[IpProfile_IsDTMFUsed]
Enables DTMF signaling.
 [0] Disable = (Default)
 [1] Enable
First Tx DTMF Option
first-tx-dtmf-option
[IpProfile_FirstTxDtmfOption]
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.
Note:
 When out-of-band DTMF transfer is used ([1], [2], [3], or [5]), the
DTMFTransportType parameter is automatically set to 0 (DTMF
