Video ports can be converted to voice ports to enable maximized
usage of the system’s resources.
The conversion ratio is 1:5, up to a maximum of 400 (80 x 5) voice
ports. The voice ports are used to connect VoIP and PSTN
participants.
18 Move the slider to the required setting.
The slider moves in multiples of two, converting video ports to voice
ports in groups of two, with each video port converting to five voice
ports. The minimum number of voice ports that can be allocated is 10
(2 video ports x 5 voice ports/video port).
All available ports are initially allocated as video ports at CIF

Modifying an ISDN/PSTN Network Service
To Modify an ISDN/PSTN Network Service:
1In the RMX Management pane, click the ISDN/PSTN Network
Services ( ) icon.
2In the ISDN/PSTN Network Services list, double-click the ISDN or
right-click the ISDN entry and select Properties.
The ISDN Properties dialog boxes are displayed. They are similar to
the Fast Configuration Wizard’s dialog boxes. For more information see
"To Add an ISDN/PSTN Network Service:” on page 12-45.
If the system runs out of voice ports, voice endpoints cannot connect to
available video ports. Conversely, video endpoints cannot connect to available
voice ports.
The maximum number of video ports displayed in the dialog box is taken from
the license key. Only this number can be converted into voice ports.
Changes made to any of these parameters only take effect when the RMX unit
is reset. An Active Alarm is created when changes made to the system have not
yet been implemented and the MCU must be reset.
