Appendix B: Access list

This appendix provides guidelines for configuring access lists to facilitate basic Avaya IP
Telephony functionality.
The ports used by the Avaya call server are fairly fixed and well known. The ports used by the
endpoints are more variable and random. As a result, it is simpler to tailor access lists based on
call server ports.

Notes
The C-LAN uses UDP
port 1719 for endpoint
registration (RAS).
The C-LAN uses TCP
port 1720 for H.225 call
signaling.
This is to facilitate IP
trunking between two
Avaya call servers, and
must be done for each
IP trunk.
This is one way to
facilitate audio streams
between MedPros and
endpoints.
