OK. I've tried Russel's devstate function and also
SIPPEER(ext:curcalls) function but they have the same problem.
Devstate shows only called SIP extensions as BUSY, but caller is not,
and SIPPEER(ext:curcalls) shows only call count 1 on called extension,
on caller is still 0. So if I make a call for example from sipext1 to
sipext2 the devstate shows NOT_INUSE on sipext1 and BUSY on sipext2,
but in real world they both BUSY, also with curcalls, on sipext1 the
call count is 0, and on sipext2 is 1.

And in dialplan I can only test the CALLERID(num) or CALLERID(name)
but they are user setable, so if some user changes it, I must to
modify my dialplan.

Another way?
