Can anybody please help?
When you ask a question like this, you should consider your audience. This is a Vicidial forum. Vicidial does run on Asterisk. Vicidial does have a very recent Asterisk 13 link. But to be real: The Asterisk community is an order of magnitude larger than the Vicidial community. I would strongly suggest you take a question like this to the Asterisk community sites and see if there are some people with direct experience there. Even the FreePBX community is likely to be helpful. There are many different .iso's that install FreePBX with complete Asterisk-enable environments. Some must include OPUS and it wouldn't be a stretch to expect some of them to also include WebRTC.
But you may get lucky here. I'm just saying that this is a niche (and not that huge). If you wait a few months for WebRTC to be more prevalent (after ViciPhone is fully published) you may have more luck.
