I am working on a project with voip phones. All sites in this project are connected to the LAN with cat5 or fiber. One site is unable to call out on their voip phones. We can call into them and all other devices have connectivity. Configs have been checked and I am the "new set of eyes" on the issue. There is a firewall between us. Could that be blocking something? If so,what would I look for? Any insight would be appreciated. I will check back off and on tomorrow to answer any additional questions.
