[CallPriorityMode]
User's Manual
Defines the Conference Identification string.
The valid value is a string of up to 16 characters. The default is "conf".
For 3-way conferencing using an external media server: The device
uses this identifier in the conference-initiating INVITE that is sent to the
media server when the Enable3WayConference parameter is set to 1.
When using the Mediant 1000 Media Processing Module (MPM): To join
a conference, the INVITE URI must include this Conference ID string
preceded by the number of the participants in the conference and
terminated by a unique number. For example:
INVITE sip:4conf1234@10.1.10.10.
INVITE messages with the same URI join the same conference.
Enables the use of different RTP ports for the two calls involved in a
three-way conference call made by the FXS endpoint in the initial
outgoing INVITE requests.

[0] Disable = First and second calls use the same RTP port in the
initial outgoing INVITE request. If a three-way conference is then
made, the device sends a re-INVITE to the held call to retrieve it and
to change the RTP port to a different port number.
For example: The first call is made on port 6000 and placed on hold.
The second call is made, also on port 6000. The device sends a re-
INVITE to the held call to retrieve it and changes the port to 6010.

[1] Enable = First and second calls use different RTP ports in the
initial outgoing INVITE request. If a three-way conference is then
made, the device sends a re-INVITE to the held call to retrieve it,
without changing the port of the held call.
Notes:

When this feature is enabled and only one RTP port is available, only
one call can be made by the FXS endpoint, as there is no free RTP
port for a second call.

When this feature is enabled and you are using the Call Forking
feature, every forked call is sent with a different RTP port. As the
device can fork a call to up to 10 destinations, the device requires at
least 10 free RTP ports.

This parameter is applicable only to FXS interfaces.
MLPP and Emergency E911 Call Parameters
Enables priority call handling for all calls.

[0] Disable (default).

[1] MLPP = MLPP Priority Call handling is enabled. MLPP prioritizes
call handling whereby the relative importance of various kinds of
communications is strictly defined, allowing higher precedence
communication at the expense of lower precedence
communications. Higher priority calls override less priority calls
