Problem with multiple call

[rmandis]

Hi,
We've an installation where operator need to ask to multiple call using the desktop app that is programmed to use an yealink t58w phone as audio device. Atteched to this phone there's an yealink WH63 dect headset.

If the operator try to answer to one of multiple call entering there isn't audio, only if he answer to all (clicking to the pop-up on the desktop app) there are audio traffic between the intelocutor and the last call answered, others are in call waiting.

I'm unable to reprodute the same problem in other installation

The only parameter that I don't undestand is about " Block Remote Tunnel Connections (3CX App connections with Tunnel enabled & SBC will be blocked)" ...is it possible that this will block the correct way to answer?

The problem was solved!
When you attach an headset type WH63 to a yealink phone line T48 or T58 you need to use the usb interdace marked as PC otherwise multiple call doesn't function.
With "stupid" phone you can use the usb interdace marked as phone.

So in this case you cannot use the headset with two device as technical specification say.
Remember: this problem appears only with multiple simultaneous incoming call
