
[0] Disable (default).

[1] Enable
Determines whether the device uses the value of the incoming SIP
Reason header for Release Reason mapping.

[0] Disregard Reason header in incoming SIP messages.

[1] Use the Reason header value for Release Reason mapping
(default).
Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the SDP's 'silencesupp:off' attribute.

[0] = Disregard the 'silecesupp' attribute (default).

[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 = X-Channel header is not used (default).

[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

[-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.
