asterisk users - Mar 2005 - asterisk + outlook + omniis TAPI driver

Hi:

I was wondering whether there's a way to bridge two conference bridges
using Asterisk.

I want to allow a meetme conference to join an external conference
over the PSTN. One way of doing it, in theory, would be to use Omniis'
TAPI driver and place a CAPI call to the ISDN line (external conf.),
while the driver calls an internal meetme conf on asterisk over SIP.
Didn't have luck with it though.

Any other ideas? Or suggestions on how to achieve the above?

Ta,
