Hello dear forum members,
i’m rather new to asterisk and telephony in general. I have to do quite a large project, which will be involving asterisk. Maybe a small introduction would be nice…
I work for a company with several call-centers. At the moment we use “commercial” solutions for our outbound calling. Expensive pbx soft\hardware and a really expensive predictive dialer (1500 euro’s a seat!). Cause we’ve got about 200 seats, we’d rather not pay 1500*200 (as u might imagine). Anyway, we’ve been looking around to replace our stuff and found asterisk, which we think is AWESOME! Anyway, cause i’m rather new to all this stuff (don’t work here that long) and i’m going to roll out this project, i really am in need for some information! So, if anybody has some answers to my questions that would be great!
Ok, the following is what i have in mind for this project (questions in there as well) : And excuse my english here and there, not a native speaker…
We’ve got several call centers, as mentioned. We’d like to connect all of them to one fat pbx system, or several interconnected pbx systems. At the moment we have analog old skool phones. Would it be wise to continue using those, or is it better to use voip internal with regular phone lines to the outside? What is the advantage of using voip inside against analog (except for the wiring)? And, if we’d use analog lines, do i need a digital E1 card for the outside world and an analog card in my pbx? Or can i also use voip with my analog phones, by hooking those up to a analog card that u can buy at digium? Some hardware advice would be highly appreciated. Cause, as mentioned before, i’m not a phone hardware master (yet;)).
Is it possible to connect pbx-s from several buildings, so we have one “big” pbx? Or can i just build an ultra fat pbx and connect all the buildings trought some vpn with it? I noticed u need quite some big hardware to get good quality on concurrent phone calls. So, maybe clustering it would be a better idea, since we might have 150 or more concurrent calls at a time?
Oh yeah, not really un-important: what distro is advised? I assume it’s best to run the box without the qui right? Saves recourses…
Then the part of predictive dialing. I’ve seen gnudialer, but that is not totally covering our needs. It’s planned to build that one ourselves. Cause this company uses mainly m$ products, that stuff will be coded in c#. Is talking trough the sockets the way to go? Cause i can imagine with dialing 100s of phone numbers a minute, asterisk might not find that amusing. Does anybody have any experience on that?
Geez, i realize it’s quite a long post… Well, sorry… Just so full of questions and really enthusiastic to get going with asterisk. Main question of this post is actually: analog or voip (internally)? Cause i first have to decide what hardware to buy, then build a test environment, code some api stuff and implement it. Oh yeah, if i asked anything dumb in this post, don’t hesitate to call me a dumb ass… i can live with that, as long u give me some urls to read;)
tnx!
