Hi, all. I've got a T1 through Choice One Communications (www.choiceonecom.com), a provider in the US northeast. I recently tried to switch to ISDN on it -- and failed miserably. I've posted my config files, and nobody's seen anything obviously wrong. Has anyone else used their ISDN T1's? If so, would you be kind enough to send me your zapata.conf and zaptel.conf files? Thanks! -Ken
