Hi, Thanks to Matt and Steve for replying to my post :-) . Steve, I would really like to know more about your code like how it exactly works and how resource (cpu and memory) intensive it is.
Matt, following are the details you asked for: I want my system to detect atleast 80% of the answering machines and that too within 1-3 seconds, just like dialogic boards. Otherwise there won't be much reason to replace the existing predictive dialer system with Asterisk. We're going to have 24 to 48 lines initially and it'll definitely be T1. We've not yet finalised which cards (Digium, Sangoma or if possible Dialogic) to use. Also, we'll be writing our own Predictive dialer application which will talk to Asterisk using its Manger API interface. I would be really grateful if you could guide me on the above and also throw some light on the following: - Does Asterisk support the Dialogic D/480JCT-2T1 board (That's what our current system is using) ? - Which is the best T1 card for use with Asterisk?
