Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the SDP's 'silencesupp:off' attribute.

[0] = (Default) Disregard the 'silecesupp' attribute.

[1] = Handle incoming Re-INVITE messages that include the
'silencesupp:off' attribute in the SDP as a request to switch to the
Voice-Band-Data (VBD) mode. In addition, the device includes the
attribute 'a=silencesupp:off' in its SDP offer.
Note: This parameter is applicable only if the G.711 coder is used.
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.
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, 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
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
Profile table, see Configuring Tel Profiles on page 319.
Note: If this functionality is configured for a specific profile, the settings
of this global parameter is ignored for calls associated with the profile.
