Hello @ITspteam

What version PBX did you upgrade to and what is the version of the client? You can see the exact build of the 3CX PBX on the dashboard under the information column.
Also what IP phone are you using? Is it running the supported firmware and the default 3CX template?
Is the phone on the same LAN/Subnet as the phone and the PBX?

PBX Version: 15.5.0
version of the client: 15.5.12227.5
what IP phone are you using: Snom 715
Is it running the supported firmware: 8.9.3.88
Is the phone on the same LAN/Subnet as the phone and the PBX: Yes

Are you using the default templates for these phones? Also do the clients work normally in softphone mode?

 

[ITspteam]

Are you using the default templates for these phones? Also do the clients work normally in softphone mode?

yes default templates deployed from 3cx management console...

and i am able to use client normally as softphone

Try to factory reset and re-provision the phone to see if that resolves the issue as i cannot replicate it on my side. Also try sending a new welcome email to the client. What is the IP range you are using?

 

[ITspteam]

I will reset the phone and then re provision them. and get back to you.

HI i have reset the phone and done re provisioning, and no luck. Still the same

What is the IP address of the phone the PBX and the PC the client is on?

I thought the title was amusing because Nick Galea has said that "The CTI in the softphone will be removed"
https://www.3cx.com/community/threa...alog-being-displayed-by-windows-client.57398/

I understand that the WebClient will soon be able to be a softphone, but will still be able to control the deskphone.

Yiannish - could you confirm whether or not the 3cxClient will continue to be able to control a deskphone?

As far as i am aware there are no plans for removing the ability of the web client to control supported IP phones in the immediate future.

Hi Yiannish
I appreciate the response, but my question was about 3cxClient for Windows, rather than webclient.

 

[palmaz]

Yiannish, will the ability to control deskphone be removed from the 3cxClient/3cxPhone for windows?

 

[YiannisH_3CX]

No, i think you misunderstand CTI. CTI means computer telephony integration and uses CSTA going forward. If people want to use CTI, they must use the web client.... The CTI in the softphone will be removed. I hope that makes it clearer....

In the same URL above, Nick Galea said said that both CTI and CSTA will be removed:
"the windows client will not support CSTA"
"The CTI in the softphone will be removed."

In simple terms, will 3cx Client for Windows be able to control a deskphone, or will this function be removed and it only be a softphone?

My hope is that when windows softphone is rewritten, it will support CSTA and continue to be able to control a deskphone.
