AudioCodes Mediant 800 - MLPP and Emergency Call Parameters

CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
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.
