How do I need to configure my firewall for easybell VoIP and SIP trunking?

We explain how to configure your firewall for easybell VoIP and SIP trunking.

Please release Port 5060 up to 5064 for TCP and UDP, and also Port 10000 up to 50000 for UDP.

A release for certain IP addresses is not possible, because we are using different ones depending on location and load.
