Hi Gordon,

A Voip capable PBX seems a good idea, although I'm not sure if it
would fit all requirements - I might have forgot to mention some:

a) the ability for employees of the same company in diferent offices,
calling each other for free, ringing exstension xxx in order to speak
to Mr. Smith, etc
Would a PBX allow this? Or only if the PBX had its own extension
connected to the Voip provider? (Does such device exist, or am I day
dreaming?)

b) the ability of employess to both receive and make PSTN calls
(suppose the company has already PSTN numbers, which their clients
already know, or they have a local cost number, which should allow
clients to speak to at least some of the employees; besides, some
information, and paid tech support support numbers, can only be
dialled out through a PSTN line)

I'm assuming there already loads of sophisticated analogue phones -
it's not for me, it's for a friend.

8 port ATAs - of which I found only the SPA 8000 - was big news to me.
If not applied in this scenario, I'm sure I'll find a use for it :-)


An SPA3102 with multipled ports, would be ideal.

I think I'll go with the prebuilt, after I've found it ;-)

Thank a lot Gordon!

Best,
