Thank you very much for your time and this valuable information. I will give it a try and report!

Hello Stefan,

If your VoIP app in Odoo is showing Demo Mode, it usually means that the SIP/WebRTC registration is not fully established, even if the websocket connection is working.

In Odoo, VoIP requires proper WebRTC-compatible SIP configuration on the Asterisk side (including WSS, DTLS, codecs, and SIP transport settings). A working SIP client like Linphone does not always guarantee compatibility with Odoo’s softphone.

You may want to check:

• WebRTC (WSS) configuration in Asterisk (not just basic SIP)
• Proper SIP transport (WSS vs UDP/TCP)
• User/endpoint configuration for WebRTC support
• SSL certificates and domain matching for secure connection

If these are not fully aligned, Odoo will fallback to Demo Mode.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion
