I can't make a call - CTI mode 3cx client

[maciej.n]

Hello,

I still have a problem with 3cx client in my company. We can't call to the inside users and external numbers when we click "call" button. This button looks like it was a disable (screen):

All desktops have the same hardware and network configuration (LAN).

System: Windows 7 pro 64bit
Client: 3cx Phone for Windows 15.5.12227.5
Phone: Fanvil X3S
Phone Frimware: 2.4.0.5572

I try reinstall this software and turned off antyvirus and reset phone to factory defaults, without success.

Anyone help is welcome.

Hello @maciej.n

Can you call if you switch the client to softphone mode? Also can you call directly from the IP phones? Is the PBX local to the clients and phones? Have you tried using the web client? Can you replicate the issue then?

 

[maciej.n]

Everything works fine on softphone mode. I can call directly from Fanvil phones. Yes PBX is the local system. Everything works fin on web client too.

This issue concerns only cti mode on 3cx client.

It looks like the client cannot reach the phone via http and the command does not reach the phone. Are the clients and the phones in the same subnet?

 

[maciej.n]

Yes, all clients and the phones in the same network.

From the PC the affected clients are installed can you access the web interface of the phone?

 

[maciej.n]

Yes, I have access.

Not sure that the issue could be without looking at the communication between the phones and the client but i would recommend using the web client going forward for controlling phones which uses CSTA and is a more advanced way to do so.
