User's Manual 53. Configuration Parameters Reference
Parameter Description
EMS: X Channel Header
[XChannelHeader]
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
Web/EMS: Progress
Indicator to IP
[ProgressIndicator2IP]

[-1 ] Not Configured = for ISDN spans, the progress indicator (PI) that
is received in ISDN Proceeding, Progress, and Alerting messages is
used as described in the options below. (default)

[0] No PI = For IP-to-Tel calls, the device sends 180 Ringing SIP
response to IP after receiving ISDN Alerting or (for CAS) after
placing a call to PBX/PSTN.

[1] PI =1, [8] PI =8: For IP-to-Tel calls, if the parameter
EnableEarlyMedia is set to 1, the device sends 180 Ringing with
SDP in response to an ISDN Alerting or it sends a 183 Session
Progress message with SDP in response to only the first received
ISDN Proceeding or Progress message after a call is placed to
PBX/PSTN over the trunk.
Note: This parameter can also be configured per IP Profile (using the
IPProfile parameter) and Tel Profile (using the TelProfile parameter).
[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: This parameter is applicable only if SRTP is used.
[NumberOfActiveDialog
s]
Defines the maximum number of concurrent, outgoing SIP REGISTER
dialogs. This 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.

This parameter applies only to outgoing REGISTER messages (i.e.,
incoming is unlimited).
EMS: Transparent Coder
On Data Call
[TransparentCoderOnDa
taCall]

[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
