MP-11x & MP-124
Parameter Description
regardless of the origin field.

[1] Enable = The device negotiates only an SDP re-offer with an
incremented origin field.
Web/EMS: Subject
[SIPSubject]
Defines the Subject header value in outgoing INVITE messages. If not
specified, the Subject header isn't included (default).
The maximum length is up to 50 characters.
[CoderPriorityNegotiatio
n] Defines the priority for coder negotiation in the incoming SDP offer,
between the device's or remote UA's coder list.

[0] = (Default) Coder negotiation is given higher priority to the
remote UA's list of supported coders.

[1] = Coder negotiation is given higher priority to the device's (local)
supported coders list.

Note: This parameter is applicable only to the Gateway/IP-to-IP
application.
Web: Send All Coders on
Retrieve
[SendAllCodersOnRetri
eve]
Enables coder re-negotiation in the sent re-INVITE for retrieving an on-
hold call.

[0] Disable = (Default) Sends only the initially chosen coder when
the call was first established and then put on-hold.

[1] Enable = Includes all supported coders in the SDP of the re-
INVITE sent to the call made un-hold (retrieved). The used coder 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.
Web: Multiple
Packetization Time
Format
EMS: Multi 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
[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- Enables the inclusion of the P-Charging-Vector header to all outgoing
