Hi all, I have recently started using 3CX and trying to use different voip providers to test functionality! I have recently got the SIP config file from freephoneline.ca I am able to add the voip provider and have is succesfully registered, and can successfully make outgoing calls. I am however not able to receive any incoming calls. when checking on frepehoneline portal, it shows connected with user agent 3cx phone system. when i dial the number, it rings twice and gets disconnected. Any guidance/suggestion? I also have a voip.ms account and am able to get that working fine. i am able to send/receive calls.
