We use a 2821 and an ISDN E1 in our Panama office. Calls made to international numbers fail during setup. Not all calls fail. Seems that all calls to the US are ok, 50% of calls to Latin American countries fail, and 100% calls to the Carribean fail. ISDN debugging shows that CW is terminating the call (normal call clearing). It seems impossible to get any ISDN switch support from CW Panama. Does anyone have a good sample CW Panama gateway configuration, or does anyone else have this same problem?
