We have a BCM 400 rls 3.7 with a Sonic Wall Router. We turned NAT on in the router to allow for a public static IP address to hit LAN 1. We opened up all the ports necessary for the Unified Manager to work and it does. We can access the Unified Manager and make changes remotely. With an IP phone we are able to connect to the BCM but it wont fully connect, we opened up port 7000 for the ip phone and was wondering if there are more ports that need to be opened up for the ip phone to work. Any assistance will be appreciated.
