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.
The maximum number of video ports (CIF) displayed in the dialog box is taken
from the license key. Only this number can be converted into voice ports.
The slider moves in multiples of four, 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 20
(4 video ports x 5 voice ports/video port).
All available ports are initially allocated as video ports at CIF
resolution.
