WhatsApp Business Calling - WebRTC to Mediasoup

Integration
1

Meta has launched a new calling service for businesses, where an SDP offer is sent to the business whenever a user initiates a call from WhatsApp.

We currently use a WebRTC calling infrastructure based on mediasoup, but recently discovered that mediasoup does not support sdp-lite, which Meta uses for its SDP offers.

I’m looking for guidance on how to bridge this compatibility gap. What are the available options to handle or convert Meta’s sdp-lite offers to work with a mediasoup-based setup?

I have attached a sample SDP Offer from Meta.

DTLS Handshake Never Starts - Mediasoup - WhatsApp Business API Integration

Two ICE Lite agents cannot establish a connection on their own.
One peer must be a Full ICE agent to perform connectivity checks (STUN Binding requests).

Two passive peers (ICE Lite + ICE Lite) = deadlock.

As @BronzedBroth said this is not possible because mediasoup doesn’t send ICE Binding requests so this is not something that you can fix at SDP level. I understand there are some use cases for supporting full ICE in mediasoup but honestly it’s lot of work and we have other priorities.

@ankit-programmer Hi, I came across your discussion about integrating WhatsApp Business calling with Mediasoup.

I’m currently facing the same issue — the DTLS connection fails when handling WhatsApp’s SDP (ICE Lite offer).

Could you please share how you solved it? Were you able to make it work with Mediasoup, or did you switch to another solution?

Any guidance or examples would be really helpful, as I’m stuck at the same point.

Thank you!

@Sunil I created a service in Golang which acts as a bridge between Meta and Mediasoup. It helps me fullfill my requirement for the time being but I would also like remove this dependency in future if possible.
Hope this helps!
