The set h323 rtp_port_base command is used to select the starting port number for assignment of
RTP ports. When a calls are made to remote VIPs, an RTP port is opened for each call. VIP uses
the port_base as the RTP port number for the first call, the next call uses the next successive port,
and so on.
Syntax Description
port_base
The starting port number for the assignment of RTP port. If rtp_port_base is as-
signed a value of 0, the assignment of port number will be dynamic. The port num-
ber can be specified from 0 to 32767. Typically, numbers from 0 to 1023 are re-
served on most systems. The recommended value is 30000.
Example
