Is there an install script or step-by-step instruction somewhere on whaty is needed to migrate from zaptel to dahdi? I read the document that digium published which nicely states some of the differences between zaptel and dahdi but i was looking more for something like step-by-step instructions. I'm sure i will not be the only one who had this question but the wiki and google didn't help me much (or maybe everybody is still sticking with zaptel for the time being). Thanks!
