Hello community! My company currently uses the Licensed 3cx phone system, our setup is as follows: 3CX v10.0.22052.2264 SP4 (everything is up to date) Broadvox is our VOIP Provider Internet Connection is a Fiber Line 50Mbps Up / Down Cisco IP Phone SPA525G 50 +/- Remote Sales in several different states 50 +/- Internal Phones on our local network Most phones are Provisioned, some are not. Here is the issue that we are having: Intermittently ongoing calls will fade in and out, on occaision calls will drop completely. This is happening on remote as well as local phones in our office. Our standard codec is as follows: Preferred G711u Second G711a Third G722 I've changed a few of our remotes that were experiencing this fade in/out issue to codec G729, yet they still experience the "fading call" effect. Does anyone have any useful tips on how to correct this issue? Our fiber line shows to be constant in all tests, as well as our dedicated server which runs the 3cx phone system.
