Call Control Folder
Use the Call Control folder to configure parameters associated with gateway to gateway
communications and control.
The start and signalling port parameters designate the signalling ports on which
communication will be initialised and on which transmission will take place, respectively.
• The default values conform to the H.323 protocol and should always be used unless there
is a known network conflict. If a conflict is detected, refer to the H.323 protocol
specifications before making adjustments.
Use the Information section fields to modify the H.245 call start and signalling parameters,
RTP start parameters, T.38 call start, and connection timing.
Call signalling port number
Type the number of the port on which transmission will occur.
The default port number is 1720. From 4 to 65524 can be specified except FTP(20,21),
telnet(23) ports.
