I’ve been using the beta version Line2 app from Toktumi in conjunction with their phone system for a few months now and I have to say it rocks.
I was really excited about Google Voice, which is still a nice consumer app, but the Toktumi/Line2 combo is a real business solution. The base Toktumi virtual PBXgives me the power of a traditional PBX system (which we had an internal Asterisk system but Dillsmack threatened to quit if he had to keep maintaining it) with auto attendant, extensions, etc. plus new calling features like simulring, which rings any or all of my phones at once – office, cell, home, whatever – call handling – this person goes straight to voice mail, this person goes to office and cell, this person goes to straight to cell and home, etc. On top of that I get unlimited free calls throughout the US/Canada and some dirt cheap international rates, like $.02/min plus instant conference calls for up to 20 people all for only $14.95/month. Oh and did I mention they let me pick an 800 number, local number or transfer an existing number, pretty sweet.
