[Asterisk-Users] Multiple Calls with Asterisk?

[Jim Lists]

Hi All,
Please excuse my newbie questions, but figured this would be the best
place to ask. I have been reading up on VOIP and implementing Asterisk
as a PBX. I'm still left wondering if Asterisk supports multiple lines
at once? If I had one land line, voip line, and asterisk setup and 10
people called my number, would all 10 people be able to speak to their
appropriate party at the same time, or would the other 9 get a busy
signal? Also, could this work with outgoing calls? If this DOES work,
can anyone explain how it works? More importantly, at what point does
the analog line move to the VOIP line, and how is the connection
maintained? I'm sure I'm "nuking" this out, but I'm still trying to
figure out most of the acronyms related to all this stuff.

Thanks. :)
Jim
