See the following configuration for this example:
hostname(config)# interface Vlan100
hostname(config-if)# nameif outside
hostname(config-if)# security-level 0
hostname(config-if)# ip address 209.165.201.2 255.0.0.0
hostname(config-if)# !
hostname(config-if)# interface Vlan50
hostname(config-if)# nameif inside
hostname(config-if)# security-level 100
hostname(config-if)# ip address 10.100.100.2 255.0.0.0
hostname(config-if)# !
hostname(config-if)# interface Vlan90
hostname(config-if)# nameif callmgr
hostname(config-if)# security-level 75
hostname(config-if)# ip address 209.165.201.254 255.0.0.0
TFTP port is enabled for the IP address of the CallManager so that phones on the inside and outside can
download configuration files from the CallManager for initial setup. TCP Port 2000 is enabled for the
IP address of the CallManager so that skinny signaling can pass the module between the phone and the
CallManager through firewall module.
hostname(config-if)# access-list voice extended permit udp any host 209.165.201.210 eq
tftp
hostname(config)# access-list voice extended permit tcp any host 209.165.201.210 eq 2000
Apply the above access lists on the inside and outside interfaces for incoming traffic:
