Ports Used in SIP Trunking

This is a list of the network UDP ports used with SpitFire SIP trunking configurations. These ports often need to be forwarded to the IP address of the Dialer/Server so that firewalls do not block the SIP traffic. 

UDP Ports: 5060, 5065 & 5080

UDP Ports: 49152 to.... The end of the port range here depends on how many lines the Dialer is licensed for. You basically count how many lines and multiply times 2. For instance, a Dialer with 16 lines would need ports 49152 to 49184 forwarded to the Dialer's IP address.
