Nice job on this :)

I think it’s really fun how it’s all the same underlying protocols. Makes it easy to bridge these two protocols you would assume are dramatically different!

Yes, both share the same base protocol, I just wanted to play around with it for fun.

I noticed that in SIP, when a device sends an offer with sendrecv, the gateway responds correctly, but if I try sendonly or recvonly, it doesn’t seem to work only sendrecv works. I’m not sure why yet, so I’ll need to dig into it more.
