Hi! If I want to use ISDN card for connecting phones to it, that card must be HFC-S, because of NT mode. How about if I am connecting ISDN card to the external ISDN phone line (to local telephone companys s-bus) when card must be in TE mode, do I still have to have HFC-s card that I could forward incoming calls from pbx to phone(s) or could that be any ISDN card? Thank you for your answers ---------------------------------------------------------------- This mail sent through L-secure: http://www.l-secure.net/
