Hi all, I have a strange problem with my system 11 3CX server. I have an Godaddy VPS and install the server on there, so all my extensions are remote extension, the phone call works well if call was placed from any where outside. But If I make a extension to extension internal call. Call will ring but no audio after I picked up the phone call. I tried to use Both 3cx phone on IOS, Android, windows, and regular cisco phone as remote extension, but none of them works. I also found an even stranger situation is when I use the mobile 3cx, if I hit the "record" button while I'm still on the line with another internal extension, then audio works. I also tried to go to Management console and in extension configuration, selected record all phone calls on the extension, then the internal call works. My guess is, when I make it record the call, the audio traffic would forced to go through the server. Another wise, between extension to extension, audio only delivered without the server. That's probably why internal call wasn't working. If so, what should I do to make local phone calls working? It must a server config issue right? Otherwise at least two mobile remote extension would work just fine, since it has nothing to do with the CISCO phones. Please help. Thank you.
