User's Manual
Note: This parameter is applicable only to the Gateway application.
Determines whether the 'mptime' attribute is included in the outgoing
SDP.

[0] None = (Default) Disabled.

[1] PacketCable = Includes the 'mptime' attribute in the outgoing
SDP - PacketCable-defined format.
The mptime' attribute enables the device to define a separate
packetization period for each negotiated coder in the SDP. The
'mptime' attribute is only included if this parameter is enabled even if
the remote side includes it in the SDP offer. Upon receipt, each coder
receives its 'ptime' value in the following precedence: from 'mptime'
attribute, from 'ptime' attribute, and then from default value.
Determines whether the 'ptime' attribute is included in the SDP.

[0] = Remove the 'ptime' attribute from SDP.

[1] = (Default) Include the 'ptime' attribute in SDP.
Determines the device's behavior regarding call identifiers when a 3xx
response is received for an outgoing INVITE request. The device can
either use the same call identifiers (Call-ID, To, and From tags) or
change them in the new initiated INVITE.

[0] Forward = (Default) Use different call identifiers for a redirected
INVITE message.

[1] Redirect = Use the same call identifiers.
Enables the inclusion of the P-Charging-Vector header to all outgoing
INVITE messages.

[0] Disable (default)

[1] Enable
Defines the time (in seconds) used in the Retry-After header when a
503 (Service Unavailable) response is generated by the device.
The time range is 0 to 3,600. The default is 0.
Determines whether the device, upon receipt of a SIP 503 response
without a Retry-After header, behaves as if the 503 response included
a Retry-After header and with the period (in seconds) specified by this
parameter.

[0] Disable (default)

Any positive value (in seconds) for defining the period
When enabled, this feature allows the device to operate with Proxy
servers that do not include the Retry-After SIP header in SIP 503
(Service Unavailable) responses to indicate an unavailable service.
The Retry-After header is used with the 503 (Service Unavailable)
response to indicate how long the service is expected to be
unavailable to the requesting SIP client. The device maintains a list of
available proxies, by using the Keep-Alive mechanism. The device
checks the availability of proxies by sending SIP OPTIONS every
keep-alive timeout to all proxies.
If the device receives a SIP 503 response to an INVITE, it also marks
that the proxy is out of service for the defined "Retry-After" period.
Determines the device usage of the P-Associated-URI header. This
header can be received in 200 OK responses to REGISTER requests.
When enabled, the first URI in the P-Associated-URI header is used in
subsequent requests as the From/P-Asserted-Identity headers value.
