SIP User's Manual
Determines whether the ptime header is included in the SDP.
[0] = Remove the ptime header from SDP.
[1] = Include the ptime header in SDP (default).
Enables or disables usage of the User Information loaded to the
device in the User Information auxiliary file. (For a description on
User Information, refer to ''Loading Auxiliary Files'' on page 192.)
[0] Disable = Disabled (default).
[1] Enable = Enabled.
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 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
"a=silencesupp:off" in its SDP offer.
Enables / disables the usage of the 'rport' parameter in the Via
header.
[0] = Enabled.
[1] = Disabled (default).
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 which
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 doesn't include 'rport' tag, the destination port of the
response is taken from the host part of the Via header.
If the Via includes 'rport' tag without a port value, the destination port
of the response is the source port of the incoming request.
If the Via includes 'rport' tag with a port value (rport=1001), the
destination port of the response is the port indicated in the 'rport' tag.
Determines whether the x-channel SIP 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 = SIP x-channel header is not used (default).
[1] Enable = SIP 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
