Hi, I like the 3cx-Phone very much, but i have a little problem and I hope you can help me! (and i hope you understand my bad english. ) Following configuration: 3cx logs in into my FritzBox 7390. And my FritzBox has the Data of the Voip/SIP-Account saved. The Calls are working very well with the software. The problem: Everytime i try to transfer the call it says "server error". It would be really nice if someone is able tohelp me. If you need any more data, I will post them here!
