parmeter.
Enables the device to add the SIP X-Channel header to outgoing SIP
messages. The header provides information on the physical Trunk/B-
channel on which the call is received or sent.

[0] Disable = (Default) X-Channel header is not used.

[1] Enable = X-Channel header is generated by the device and sent
in SIP INVITE requests and 180, 183, and 200 OK responses. The
header includes the Trunk number, B-channel and the device's IP
address, using the following syntax:
x-channel: ds/ds1-<Trunk number>/<B-
channel>;IP=<device's IP address>
For example, the below shows a call on Trunk 1, channel 4 of the
device with IP address 192.168.13.1:
x-channel: ds/ds1-1/4;IP=192.168.13.1
Global parameter defining the progress indicator (PI) sent to the IP.
You can also configure the functionality per specific calls, using IP
Profiles (IpProfile_ProgressIndicator2IP) or Tel Profiles
(TelProfile_ProgressIndicator2IP). For a detailed description of the
parameter and for configuring the functionality, see Configuring IP
Profiles on page 393 or Configuring Tel Profiles on page 428.
Note: If this functionality is configured for a specific profile, the settings
of this global parameter is ignored for calls associated with the profile.
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.
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.
Note:

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).

[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
1005
