User's Manual 67. Configuration Parameters Reference
Version 6.8 861 Mediant 500L MSBR
Parameter Description
[EnableRport]
Enables the usage of the 'rport' parameter in the Via header.
 [0] = Disabled (default)
 [1] = Enabled
The device adds an 'rport' parameter to the Via header of each
outgoing SIP message. The first Proxy that receives this message
sets the 'rport' value of the response to the actual port from where
the request was received. This method is used, for example, to
enable the device to 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.
Web: Enable X-Channel
Header
EMS: X Channel Header
CLI: 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, Bchannel,
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
CLI: prog-ind-2ip
[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 this parameter and for configuring this
functionality in the IP Profile table, see Configuring IP Profiles on
page 332 or in the Tel Profile table, see Configuring Tel Profiles on
page 327.
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: This parameter is applicable only if SRTP is used.
