Hello all, I am pretty new to VOIP. My boss has requested that I do some digging and find out what would be the most cost effective solution. Asterisk is an awesome piece of software, however as I am new to VOIP I am unsure of a lot of things.
WARNING***TYPICAL N00B QUESTIONS APPROACHING
How would one go about finding a decent VOIP service for a medium sized business with multiple locations. I have found many inexpensive services; however they only allow one active call at a time. We have a collections department that will be making calls constantly. We will need to be able to have at least 30 active calls simultaneously and need an inbound number that anyone can call from a standard phone. Preferably an 800 number. Also, since we have 4 locations would it be possible to make 4 Asterisk boxes that work together on that network? So say some one at location A can pick up the phone and dial an extension to get someone at another location.
EDIT: I guess it might help if I state where our locations are. All 4 are in Central and Northern Indiana (USA).
Thanks in advance for any info that is given.
