Hi Christopher,
This may seem like a daft suggestion, but why not set the asterisk box 
to use ss7 signaling ?
It sounds like you're using the same style of hardware that I am (ie, a 
server with a TE410P card)
so it shouldn't be hard to configure asterisk to use ss7 instead of ISDN 
PRI.

Regards,
Mark.
