3CX Windows Client (Legacy) "3CXPhoneforWindows16.msi" with 3CX v20

[honey_bumpkins]

I'll pop this here to assist others:

I have a use case where the users need to use the App (not Webpage or PWA), since v18 app dosent work well with v20 - downgraded to v16.

Downloaded and Installed v16 initally you can't provision as no attachment on the welcome email.

Login to 3CX > Admin > Advanced > Parameters >
search "ATTACH_3CXCONFIG_WELCOMEEMAIL"
change from 0 to 1

optional: "SEND_WELCOME_ON_1ST_RESTORE"
change from 0 to 1

Login to 3CX > Admin > Users > select users > Reset button now sends welcome email with provisioning config file.

Thanks, this was a huge help. Getting my coworkers away from the v16 Legacy App will be hard at some point with the stability and ease of use when comparing to the 3 (?) different kinds of Apps 3CX tried since then.

On the same subject (v16 Legacy app paired with v20) we have just upgraded our PABX from v18 to v20. It still seems to work ok "as is" but for some reason the call pickup function (ie picking up an incoming call for another ringing extension) has just disappeared, all things being otherwise equal. The menu item (right click on the ringing extension) is simply not there anymore.
Does that ring a bell with anyone ?

Are those users at least Reception? https://www.3cx.com/docs/manual/access-roles/

That was it - seems "users" had this enabled in earlier versions. Anyway THANKS

The "user" role is no longer customisable, so if a user had the option for operation previously, this will have reverted back to the defaults the user role in Version 20, which would explain why they could do it in Version 18.

HI,
I am so glad I found this. We are not looking forward to upgrading the clients and would prefer to use the v16 client.
I changed the params as per your post and got the config file in the mail.
However, I am getting a Registering Failed error.. not sure why. any thoughts
Is your system local install or cloud hosted? Just wondering if that might cause some differences.
I am testing with cloud 2month test account, but our prod unit is onprem vm.

@uhpadmin Hi there.
V16 app is no longer supported for the new PBX (that is why you can't see in the APPs of the Web client to download), so if you got updated and the apps were there, and worked that ok, but keep in mind that you should not use that app as it is a legacy application and we no longer update/maintain it.
Use the latest V20 Windows app or PWA/Webclient
