I have 12 snom 300 phones and they all have the same problem. Inbound calling goes fine, but outbound gives the message "forbidden" on the display of the snom 300's. The firewall check in 3cx is all good (green text), so I don't see what the problem is. Below you find an verbose log from 3cx from an outbound call:

It seems that the VoIP Provider is rejecting the call with a "603 Declined". You should ask the VoIP Provider's technical support to make a trace of failed call, and tell you which part of the SIP INVITE message that they are receiving is not accepted by their platform.
