I was reading TechCrunch recently and found out that more companies are moving into marketing virtual numbers for small businesses and startups. Vumber, a company that originally targeted marketing a throwaway number for people on dating websites, is moving into the virtual number space that targets businesses. It seems like Vumber can reach more customers this way, and I think it's a really great move. I don't believe Vumber has the capability to route calls to certain extensions like a virtual PBX service does, but in terms of just having a secondary phone number, it seems to do the job quite well.
I think it all boils down to cost. If company A can get the same service for less then there's no reason not to start using that service.
Very true, if you can find a <a href="http://virtual-pbx.choosewhat.com/" target="_blank" name="ChooseWhat Virtual PBX Comparison">virtual PBX service</a> for the same price or less than a Vumber, why not try it out?
