I have a 3640 with NM-8BRI and 6MICA-MDM and everything is working fine. ISDN DDR, Async Dialin, Async Dialout.
I'd like to add ISDN Dilaout for our users, I've tried setting connecting with Hyperterminal, setting
ATS29=8
ATDI 034343443344
I am using Dialout EZ Release is 4.3 for async dialout and it is working fine. So the DialOut is ok.
