3.3 Advanced Gatekeeper Configuration
I. Configuring the RAS signaling port of the gatekeeper and the endpoint
TCPCall signaling port
H.323 gateways and gatekeepers use RAS signaling to exchange messages. A
gatekeeper receives/transmits RAS signaling on its RAS port. The backup RAS port is
used to assist the RAS port in RAS signaling transmission and receiving.
When the gatekeeper function is enabled on an XE IP PBX, the RAS port and backup
RAS port (if configured) on the XE IP PBX are enabled for RAS transmitting and
receiving.
In H.323 basic routed call mode, the calling and called gateways exchange call control
signaling through an XE IP PBX that serves as a gatekeeper. The gatekeeper listens
the TCP connection requests transmitted when gateways attempt to establish call
control signaling channel through the endpoint TCPCall signaling port (that is, the Q931
port).
Note:
Usually a backup RAS signaling port is not required. It applies when two ports are
needed for RAS signaling transmitting and receiving. For example, some devices send
RRQ messages to port 1719 and GRQ messages to port 1718. In this case, configure
rasport as 1719 and 2nd-port as 1718.
Perform the following configuration in PS-GK view.
