Connecting an ISDN telephone

12 years 2 months ago #664 by james.zhu
hello, friend:
if you set the port in NT modes, which can connect with ISDN phone, but no incoming and outgoing line. if you want to make a outbound calls with ISDNphone, at least one port should be TE and one port should be NT mode. the TE port connects with ISDN line. i think user manual has explained it. please read it. or you can go to and to find resource. it is sufficient for your case.
