Well, long ago, half a year or so, it was not possible to have
Asterisk and an external entity to listen on the same MSN. It
was possible to have them listening on different MSNs though.
But now I have had no problems with Asterisk and an external
phone together. I can answer the call where I want. The only
problem I have is the problem above. The mISDN signaling,
visible with debug on, does not seem to reach the "hint" layer
in Asterisk.
