User's Manual 44. Configuration Parameters Reference
Parameter Description
identify its port mapping outside a NAT.
If the Via header doesn't include the 'rport' parameter, the destination
port of the response is obtained from the host part of the Via header.
If the Via header includes the 'rport' parameter without a port value, the
destination port of the response is the source port of the incoming
request.
If the Via header includes 'rport' with a port value (e.g., rport=1001), the
destination port of the response is the port indicated in the 'rport'
parmeter.
EMS: X Channel Header
[XChannelHeader]
Determines whether the SIP X-Channel header is added to SIP
messages for providing information on the physical 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 channel, and the device's IP address.
For example, 'x-channel: DS/DS1-1/8;IP=192.168.13.1', where:

'DS/DS-1' is a constant string

'1' is a constant string

'8' is the channel (port)

'IP=192.168.13.1' is the device's IP address
Web/EMS: Progress
Indicator to IP
[ProgressIndicator2IP]
For Analog (FXS/FXO) interfaces:

[-1 ] Not Configured = (Default) Default values are used. The default
for FXO interfaces is 1; The default for FXS interfaces is 0.

[0] No PI = For IP-to-Tel calls, the device sends a 180 Ringing
response to IP after placing a call to a phone (FXS) or PBX (FXO).

[1] PI = 1, [8] PI = 8: For IP-to-Tel calls, if the parameter
EnableEarlyMedia is set to 1, the device sends a 183 Session
Progress message with SDP immediately after a call is placed to a
phone/PBX. This is used to cut-through the voice path before the
remote party answers the call. This allows the originating party to
listen to network Call Progress Tones (such as ringback tone or
other network announcements).
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 5. The default is 5.
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).
