Start Your Own Open Source-Based Telecom

prostoalex writes "George Ou shows how with the help of open-source VOIP server Asterisk you can start your own telecommunications company for under $6000 '...you can build a phone system that can support 72 analog telephones or fax machines, 100 IP hard or soft phones on site or remote, a T1 line to the public telco for 23 simultaneous external PSTN connections, multiple IP-based IAX trunks to multiple remote offices for seamless toll-bypass 4-digit dialing, IVR, and almost unlimited voice mail for everyone - for under $6,000 in a 1U chassis. Such a price point is easily 10 or more times cheaper than a commercial alternative,' writes George."

  1. It ain't bad, but it sure ain't scalable by Miniluv · · Score: 4, Informative

    I work for a moderate sized telephony services provider, and I can attest that getting above the single T1 "toy" deployment written about here gets really, really hard. The Digium cards are crap, there's very little documentation, and if you try and run multiple carriers then have fun. In a few years this stuff might be pretty decent, and for small office deployments its great, but other than that it is ass.

  2. The system is only a part of the cost by QuantumRiff · · Score: 4, Informative

    We just did a VOIP implementation at work this last summer, and while we did not go with asterix, we did get a pretty good price (went with shoretel). However, the biggest single cost of all, was not the T1 installation, or the servers, or the software, it was replacing phones. Replacing 65 phones at our company at about $280 each was a pretty penny. Of course, with asterix you can find relatively cheap SIP phones, but they don't have all the fancy features, LCD's, that make it easy to use, POE, etc. So a hint for all you thinking of looking at VOIP, look at 3 very important things:
    1. Yearly costs (maint, support, etc)
    2. Upgrade costs. (how much is it to add each additional person. ie. phone+system capacity+licencing+anything else)
    3. purchase costs ( for everything, T1 installation, installers, etc)
    Look in that order. Many are cheap up front, but their phones are proprietary and cost a fortune, or can't expand in the chassis.

  3. Office-class phones by glomph · · Score: 5, Informative

    Check out the Sipura SPA-841 ($90. at voxilla.com, etc.). That is MUCH BETTER than the Fujitsu 'office-class' overpriced phones in common use in my 1000-line office.

  4. Doing it now by gregmac · · Score: 4, Informative

    I'm setting up Asterisk right now for use in our small office. Actually, it's basically setup now and I'm just waiting for my phones to get here.

    Total cost for the hardware was under CDN$2000 (8 phones, 2-port fxs adapter for analog phones/fax machines, 4-port fxo card for incoming lines, and the PC). I probably spent about 40 hours total after deciding to use asterisk learning about it, configuring everything, and testing. Even at billable $60/hr, that works to $4400, which is a lot less than a comparable commercial system (I got quotes). It didn't actually cost that much anyways, since I don't get paid $60/hr. ;)

    We now have a phone system that has an IVR menu, pratically unlimited voicemail, and every other feature you'd expect in a phone system, plus when we open a branch office later this year I can use VoIP trunks to make intra-office calls pretty much free (and easy - encouraging communication between offices).

    The system we have now is getting old, to add voicemail to it is $3000 by itself, plus the time to configure it (actually, I'd probably have to get someone to come in and set it up, since I only know the basics of how to program a few features). It can't do VoIP at all (unless you were to plug something into a CO port .. but then you'd have to dial it like an external number, and the other office wouldn't be able to call an extension directly).

    This hasn't even gotten into the advanced stuff I can do fairly easily that wouldn't be possible with another system (without spend a LOT of money) -- such as, IVR status updates on system status; allowing customers to query their account balance etc.

  5. Looking at this recently. by Blapto · · Score: 4, Informative

    I've been looking at deploying a similar system in an office I work with. As far as I can see, the main advantage is thus:
    I can take calls in, on a London number, have them handled by someone in the office, who puts them through to someone just like she normally does and they go to that employee at home. Provided he/she has broadband at home, no extra cost. Brilliant. It's not going to cost us $6000 to implement, more like $300/phone and $500 for the server, we don't need a system of the scale demonstrated, and should make the money back.
    Not to mention, pretty cool!
