What I'm worried about is trying to fix it in the current code, since it will change quite a few things that are needed today, and break backwards compatibility. I've tried, but failed, in chan_sip2 :-) and that was when I was beginning to start thinking
of chan_sip3, that will break backwards compatibility :-)
But, didn't we run across that same compatibiliity issue with iax and iax2, letting both peacefully exist until some predetermined date when iax was remove?

Wouldn't the same approach work with sip3?

IAX2 was technically a different protocol. That is: it used a different
port number. However "chan_sip1" and chan_sip3 are both implementations
of the same protocol, and expected to listen on the same port 5060.

So you could run both on the same system, if one is bound to a different
port. But if a remote system calls in and asks to connect through SIP,
you have to choose, as it will typically just expect it on the well
known SIP port.

Sounds more like Voicemail and Voicemail2 situation.
