I was having an issue with my phones taking up to 15 seconds before it would actually start to ring, in my frustration I decided to remove the PSTN gateway and start over on that front. What I have ended up with is the ability to receive calls but not make them. The event log in 3CX only shows Call or Registration to #######@(Ln.90001@Patton SN4114/JO/EUI) has failed. [ V4 192.168.70.31:5060 UDP target domain=unspecified mFlowKey=1032 ] replied: 504 Server Time-out; from IP:192.168.70.31:5060. Iv'e updated both 3CX and the Patton box to the latest software\firmware available, I've created and recreated the gateway in 3CX multiple times. My outbound rule is pretty simple, all calls on any extensions are allowed to go out. Any help would be appreciated!
