User's Manual 20. Coders and Profiles
Parameter Description

To define the format of encapsulated QSIG messages, use the
QSIGTunnelingMode parameter.
 Tunneling according to ECMA-355 is applicable to all ISDN
variants (in addition to the QSIG protocol).
 For more information on QSIG tunneling, see QSIG Tunneling on
page 503.
 The corresponding global parameter is EnableQSIGTunneling.
Copy Destination Number to
Redirect Number
copy-dst-to-redirect-number
[IpProfile_CopyDest2Redirec
tNumber]
Enables the device to copy the called number, received in the SIP
INVITE message, to the redirect number in the outgoing Q.931 Setup
message, for IP-to-Tel calls. Thus, even if there is no SIP Diversion or
History header in the incoming INVITE message, the outgoing Q.931
Setup message will contain a redirect number.
 [0] Disable (default).
 [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.
