asterisk users - Apr 2010 - Taqua users out there?

Are there any other Taqua users out there?

We have a trunk to a Taqua switch through our ITSP and all outbound
calls have the ANI of the primary number on the trunk regardless of what
outbound caller-id we generate.

This is more than a little annoying, as it interferes with single-number
calling, find-me/follow-me, and other features we're using with Asterisk
1.6.

Is there anyone with expertise in what tweaking needs to be done on the
Taqua side?

And is there an open Taqua forum?

Thanks,

-Philip
