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.
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: The parameter is applicable only if SRTP is used.
Defines the maximum number of concurrent, outgoing SIP
REGISTER dialogs. The parameter is used to control the
registration rate.
The valid range is 1 to 20. The default is 20.
Note:
■ Once a 200 OK is received in response to a REGISTER
message, the REGISTER message is not considered in this
maximum count limit.
■ The parameter applies only to outgoing REGISTER messages
(i.e., incoming is unlimited).
Defines the Network Node Identifier of the device for Avaya UCID.
The valid value range is1 to 0x7FFF. The default is 0.
Note:
■ To use this feature, you must set the parameter to any value
other than 0.
■ To enable the generation by the device of the Avaya UCID value
and adding it to the outgoing INVITE sent to the IP Group (Avaya
entity), use the IP Groups table's parameter 'UUI Format'.
Enables the modification of the called and calling number for
numbers received with Microsoft's proprietary "ext=xxx" parameter
in the SIP INVITE URI user part. Microsoft Office Communications
Server sometimes uses this proprietary parameter to indicate the
extension number of the called or calling party.
