If I'm correct, you just found the problem yourself: While Stanaphone uses the
obvious "stanaphone.com" as its realm, BroadVoice uses "BroadWorks" instead, and
so you'll need to update that in your config.

Asterisk has some logic to find the realm itself, so even if you give it a bogus
realm (or no realm at all), it still manages to do the right thing.  FreeSWITCH
is far more transparent in its configuration, which IMHO is really cool, but it
also creates its share of surprises :-)
