Example Port Configurations for Voice Operations

The following examples show some of the port configurations required for voice operations.

Voice Bearer
rtp 16384 - 32767 udp
Voice Signaling
sccp 2000 tcp
Other Traffic
dhcp 67 udp (server) --> same as bootp
dhcp 68 udp (client) --> same as bootp
dns  53 udp
tftp 69 udp
Note Some protocols (such as TFTP) use dynamic port allocation, therefore Cisco recommends that you do not use an explicit deny-all statement for the filtering rules.
