[Asterisk-Users] Kind of off-topic: VoIP services and multiple callers

[Kanwar Ranbir Sandhu]

Hello Everyone,

I've been running Asterisk as our PBX for several months now, and
recently I've been thinking about using one of the VoIP providers to
lower our phone bill.  

I know that VoIP providers can supply their customers with a local
number and/or virtual numbers, and then that number/account can be used
with Asterisk (well, it depends on the provider and whether or not their
service is compatible with Asterisk).  However, I have a question: can
more than one person make/receive a call at the same using one VoIP
line?  

In the analog world this obviously isn't possible, but with VoIP, it's
just bandwidth: the more callers, the more bandwidth.  I keep saying to
myself it should be possible, but the VoIP providers don't provide any
information about this.

If five people in the office all need to use their phones at the same
time, would I need five VoIP lines, or would I only need one VoIP line?
Am I over-thinking this?

Thanks in advance,

Ranbir
