Perhaps. The above is a bit esoteric. A more realisic issue is what to
put in From, where at the moment you can't put multiple choices. So I
have to choose whether to cater to the luddites or the young. (I'm not
young, but I don't think I'm *quite* a luddite. Just saddled with a lot
of legacy stuff I don't have the option of changing or am too cheap to
change. (I *am* cheap.))
At least with P-A-I you can put both a sip and a tel. The alternative
being explored on this list of including both in normal sip signaling
would solve that.
