Parameter Description
parmeter.
Enable X-Channel Header
configure voip > sip-
definition settings > x-
channel-header
[XChannelHeader]
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
Progress Indicator to IP
configure voip > sip-
definition settings > prog-
ind-2ip
[ProgressIndicator2IP]
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.
[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.
configure voip > sip-
definition settings >
number-of-active-
dialogs
[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.
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).
[TransparentCoderOnDataC
all]
 [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
