sounds like you are having an issue with your pri libraries, if you are using stable i would reccomend making sure all your versions are the same, or if you are using cvs i would reccomend upgradng all of them to the latest and rebuild from scratch, zaptel, libpri, asterisk

Thanks mogorman it was a libpri problem
