Keypad Doesn't Pick Up calls

[andytelco]

Hi everyone,

Hope someone can help.

We have an isolated issue with two customers where their keypads won't answer calls.
What I mean by that is, you physically can't press the green button. When you do have the chance to pick up a call you then can't hung up.

We have uninstalled and reinstalled the app
Tried the web client app also and the same thing happens.

Company A is the IT company of Company B who is having the issue.

Only 1 Individual user in Company A is having the Problem and 1 Person in Company B

The firewall is okay since we have many 3cx users with this IT company.

Can anyone help?

Can you verify the following please, are there any other software that use the microphone/headset (e.g. Teams) installed and running on the two PC's? In addition, do the two users have internet connections over IPv6?
