Parameter Description
■ [0] Disable = (Default) The FXS endpoint makes the
first and second calls on 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: A first calls B on port 6000 and places B
on hold. A then calls C, 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 = The FXS endpoint makes the first and
second calls on 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.
For example: A first calls B on port 6000 and places B
on hold. A then calls C on port 6010. The device
sends a re-INVITE to the held call to retrieve it
(without changing the port, i.e., remains 6010).
Note:
■ 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.
■ The parameter is applicable only to FXS interfaces.
