I have installed 3CX Phone system. At present I have not connected to any PSTN or VOIP Providers. I am testing extensions first. When I tried with 3CX voip client it is working withing the home office. When I try from outside the office 3cx client is not work. So I was testing other soft phones and in the process I foudn X-Lite seems to be good. Now .. I am trying to use X-Lite 3.0 softphone to test extensions. It is not working. When I tried one extension with X-Lite to the other extension which is 3CX client - it is working. X-Lite is registering with phone system and line status shows green and client phone says 101 is ready, But not able to dial the other extension Please let me know if some one has done X-Lite softphone configuration to 3CX Phone system. .. thanks!
