NOTE: If using CCA 1.1 or earlier, then you will need to follow the below steps to

ensure SIP traffic goes through. Check the WAN interface configuration (note if using

PPPoE then this interface would be Dialer0, not FastEthernet0/0):

UC500#show run interface FastEthernet 0/0

interface FastEthernet0/0

ip verify unicast reverse-path

ip inspect SDM_MEDIUM out

Add the below CLI :

UC500#config t

UC500(config)#interface FastEthernet 0/0

UC500(config-if)#no ip verify unicast reverse-path

UC500(config)#interface Integrated-Service-Engine 0/0

UC500(config-if)#no ip access-group 100 in

UC500(config-if)#interface Loopback 0

UC500(config-if)#no ip access-group 101 in

UC500(config)#ip inspect name SDM_MEDIUM udp router-traffic timeout 300

UC500(config)#end
