I have used a test server with a passive card unde I4L and encountered
echo pb whe dialing out to pstn side from any IP Phone I have tested. So
I am considering to get some BRI HW with echo cancellation circuit. I
have found only card from Eicon. If my pbx extend to more than 15 lines,
I will use PRI Card so my question.

The Eicon driver for PRI seems to be CAPI Compliant if I have understood
