A sip <-> jack "hybrid" would be way cool, but while that covers the
side of the problem, it leaves the call setup and control side.

So many potential programs, so little time....
I know that one.

That would be a pair of jack ports, and to be at all usable in a
radio context it needs
to support at least "ring indicator" and ideally call termination
Being able to set up (and terminate) calls would also be kind of nice.

Perhaps a daemon that could connect multiple sip "lines" to jackd and
provided a couple of fifos
to communicate line status and to handle dialing?

This is something that has also been on my todo list for a while
(with exactly the same intended use).....
