Hi, we successfully connected an Asterisk "FreePBX" to Odoo 12.0

On incoming call it identifies the caller and a Message pops up as expected.

When we then try to answer that call we get a Javascript client error:

Odoo Client error

My guess is that the Browser tries to read a list of available devices (Speaker, Microphone) to actually do the phone call.

Question: Does the Browser need some extension/setting specially for Odoo Softphone to work?

Suggestions/hints very welcome.
