Parameter Description
destination port of the response is the port indicated in the 'rport'
parmeter.
Enable X-Channel Header
[XChannelHeader]
Determines whether the SIP X-Channel header is added to SIP
messages for providing information on the physical Trunk/B-channel on
which the call is received or placed.
 [0] Disable = (Default) X-Channel header is not used.
 [1] Enable = X-Channel header is generated by the device and sent
in INVITE messages and 180, 183, and 200 OK SIP responses. The
header includes the Trunk number, B-channel, and the device's IP
address.
For example, 'x-channel: DS/DS1-5/8;IP=192.168.13.1', where:

'DS/DS-1' is a constant string

'5' is the Trunk number

'8' is the B-channel
 'IP=192.168.13.1' is the device's IP address
Progress Indicator to IP
[ProgressIndicator2IP]
Global parameter that defines the progress indicator (PI) sent to the IP.
You can also configure this functionality per specific calls, using IP
Profiles (IpProfile_ProgressIndicator2IP) or Tel Profiles. For a detailed
description of the parameter and for configuring this functionality in the
IP Profile table, see Configuring IP Profiles on page 391 or in the Tel
Profile table, see Configuring Tel Profiles on page 388.
Note: If this functionality is configured for a specific profile, the settings
of this global parameter is ignored for calls associated with the profile.
[EnableRekeyAfter181] Enables the device to send a re-INVITE with a new (different) SRTP key
(in the SDP) if a SIP 181 response is received ("call is being forwarded").
The re-INVITE is sent immediately upon receipt of the 200 OK (when the
call is answered).
 [0] = Disable (default)
 [1] = Enable
Note: The parameter is applicable only if SRTP is used.
[NumberOfActiveDialogs] Defines the maximum number of concurrent, outgoing SIP REGISTER
dialogs. The parameter is used to control the registration rate.
The valid range is 1 to 20. The default is 20.
Notes:
 Once a 200 OK is received in response to a REGISTER message,
the REGISTER message is not considered in this maximum count
limit.
 The parameter applies only to outgoing REGISTER messages (i.e.,
incoming is unlimited).
[TransparentCoderOnData
Call]
 [0] = (Default) Only use coders from the coder list.
 [1] = Use Transparent coder for data calls (according to RFC 4040).
The Transparent coder can be used on data calls. When the device
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the coder
is not included in the coder list).
The initiated INVITE includes the following SDP attribute:
a=rtpmap:97 CLEARMODE/8000
The default payload type is set according to the CodersGroup
parameter. If the Transparent coder is not defined, the default is set to
56. The payload type is negotiated with the remote side, i.e., the
