Just a short hint (and a wild guess). Try keeping Asterisk in the voice
path, by using Dial with the appropriate parameters
(http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+Dial), like
"H" - the necessary DTMF detection hinders Asterisk from bridging the
calls externally. In my experience SIP providers do not like having two
calls from the same IP address bridged to each other, because that
somehow smells of "smartass customers" ;-)
As long as Asterisk stays in the voice path, no-one external will know
that both calls are in fact one.
