I found this site the othe day while researching toll free numbers. www.my1voice.com Looks fairly cost effective, lots of cool features and unlimited extensions. I'm not a big fan of phone automation but this might be something some of you guys with salesman should check out. One toll-free number to call in and unlimited extensions that can be directed right to cell phones, office, house.. where ever. Even if you're just one guy you could make your company look big. Even has a call history report for tracking incoming calls. One number for marketing!
Too many cool features to list here, but it can also sends an email or text of your messages.
