I have a 3CX server (free version for testing). I do not have a mail server that I can use; so I am trying to configure the 3CXPhone to work with the 3CX sever. The password is working, the Available/Away is working on the extension status page. But it shows not registered. The 3CX phone says: "CTI - No Phone Connection" There is absolutly nothing in the Sever Activity Log on why it is not registered. Here are my settings for the 3CXPhone: Account Name: TWs Caller ID: 102 Extension: 102 ID: 102 Password: this works In Office: selected 127.0.0.1 (tried external IP too, did not work) Out of Office: not selected Use 3CXTunnel when .. : not selected Re-Provisional URL: not selected Some help would be greatly appreciated.
