AudioCodes Mediant 1000B - MLPP and Emergency Call Parameters

User's Manual 1142 Document #: LTRT-27055
Mediant 1000B Gateway & E-SBC
Parameter Description
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.
