Parameter Description
is therefore, re-negotiated.
This parameter is useful in the following call scenario example:
1 Party A calls party B and coder G.711 is chosen.
2 Party B is put on-hold while Party A blind transfers Party B to
Party C.
3 Party C answers and Party B is made un-hold. However, as Party
C supports only G.729 coder, re-negotiation of the supported
coder is required.
Note: This parameter is applicable only to the Gateway application.
Web: Multiple Packetization
Time Format
EMS: Multi Ptime Format
CLI: mult-ptime-format
[MultiPtimeFormat]
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.
EMS: Enable P Time
[EnablePtime]
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.
Web/EMS: 3xx Behavior
CLI: 3xx-behavior
[3xxBehavior]
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.
Web/EMS: Enable P-Charging
Vector
CLI: p-charging-vector
[EnablePChargingVector]
Enables the inclusion of the P-Charging-Vector header to all
outgoing INVITE messages.
 [0] Disable (default)

[1]
Enable
Web/EMS: Retry-After Time
CLI: retry-aftr-time
[RetryAfterTime]
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.
Web/EMS: Fake Retry After
[sec]
CLI: fake-retry-after
[FakeRetryAfter]
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
