Hi, Sorry, this is not an answer to your question, but I would be REALLY interested how you ever made that work at-all. It there a FAQ you could point me at? How do you initiate an H.221 ISDN call via Zaptel for example? I have never heard of this feature, so perhaps this is some external Zaptel/Asterisk patch that was in your 1.2.7 build that is not in your new build?
