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.
I am testing with Polycom app IOS may be it wont handle it
