1. Fuck you faggots trying to sell your shit services here.
2. It's a lot of work to make this work well. I think this is going to be my first serious post on this forum...
You need a few things:
- A PBX like Asterisk. If you don't know what a PBX is, it stands for Private Branch Exchange. Asterisk is a software PBX (it routes phone calls via software, not analog phone lines).
- SIP (Session Initiation Protocol) Trunking. A SIP trunk is something that is going to connect your VoIP based communication on your PBX to a traditional PSTN (Public Switched Telephone Network) so that you can communicate with landlines.
-A block of DID's. DID (Direct Inward Dialing) numbers that aren't already flagged as invalid VoIP numbers by Craigslist.
Wikipedia said:
In DID service the telephone company provides one or more trunk lines to the customer for connection to the customer's PBX and allocates a range of telephone numbers to this line (or group of lines) and forwards all calls to such numbers via the trunk. As calls are presented to the PBX, the dialed destination number (DNIS) is transmitted, usually partially (e.g., last four digits), so that the PBX can route the call directly to the desired telephone extension within the organization without the need for an operator or attendant.
Craigslist wants you to be using a real landline or cellular telephone, this is why something like gvoice numbers do not work - they do not want you to use a free VoIP service to bypass their verification process.
Basically once you have this setup, you can have all of the numbers forward to a singular softphone (for VoIP) or even to your landline/cellphone. You'll be able to create as many accounts as you want until you run out of numbers. All of the numbers you purchased (the DIDs) will via SIP trunking end up at your PBX, which will delegate the calls however you tell it to. This obviously is not set up for receiving text messages, but last I checked Craigslist required a phone call OR an SMS for verification. If for some reason they only require SMS now, ignore everything above.
This is only one of the challenges of advertising on Craigslist, however. You also need a good supply of proxies. I find that trying to geolocate your proxy to the city which you're trying to post in helps. I stopped doing Craigslist for this reason specifically - the PVA's weren't the biggest problem, it was getting enough/appropriate proxies. The telephone number stuff is easy in comparison to that.
Of course, a couple of years back you didn't need a phone number OR a proxy.
Ah, the good old days...
I hope this helps.
