Mediant 500 MSBR
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.
