I setting up new service in Austrialia with a cube and Verizon. I can take incoming calls but outgoing calls are failing. I've tried with other codec options
my dialpeer is simple
dial-peer voice 2000 voip
description Outound for Verizon Voip Service
session protocol sipv2
session target ipv4:172.30.201.11
voice-class sip options-keepalive up-interval 100 down-interval 50 retry 6
voice-class sip bind control source-interface GigabitEthernet0/0
voice-class sip bind media source-interface GigabitEthernet0/0
Any help would be appreciated.
My messages and error debug on.
I would suggest to move your thread to IP telephony forum to get better help.
