| You don't even need a full computer. If you want to play with it, you can download a VMware image of Trixbox and give it a test drive. VMWare player is free so it won't cost you any money to test it out. Of course, you will only be able to play with VoIP methods, but you can install free Softphones and play around with it. If you think it will do what you want, then take the next step and decide if you want to go with PSTN lines over VoIP lines. Personally, I would suggest going to at least one or two PSTN lines, but again, that depends on what you plan on using it for (I'm assuming business). That way, you have your dedicated high quality connections, and if needed you can add additional VoIP lines to higher call volumes a very little monthly fees.
rixride is right about VoIP trunks. You have to be careful with them in a production environment. Customers aren't happy when they can't hear you, or you can't here them. And without a router that can do traffic shaping, you might find that downloading a file while talking on the phone could cause problems. But, you have to compare costs. You might find that getting an additional internet connection just for VoIP is more cost effective than purchasing 4 PSTN lines from your local provider. example for my area:
4 PSTN lines = $25/mo + $15 each additional = $70/mo
1.5Mb DSL = $20/mo, 4 line VoIP = $11/mo for a total of $33
Not to mention, you don't have to buy a $200-300 FXO card. |
