Looking for some PBX advice

[SilverNodashi]

Hi,

We need to connect staff in 3 or 4 offices, 2 or 3 people per office
to a central phone system, where all the incoming lines are in 1
office, and the operator should be able forward calls to any extension
in any office, or the caller should be able to select a destination
from a prompt.

I'm thinking Astrisk..... but I've never worked with it, and teleco's
isn't our game really. Our current Avaya switchboard doesn't have a
VOIP module, and and it's apparently a rather expensive upgrade.

Can anyone please give me some pointers, and possible offer some
support when needed in the Alberton / JHB area?

To get started, what would I need for such a setup? We all have
Android / Blackberry handsets so I'm thinking we could use them as
VOIP handsets as well, but I'll need a few cordless (either analogue
or digital, please make a recommendation?) in 2 of the offices. All
the offices have at least a 4MB ADSL line and I'l sure we can upgrade
them all, or get extra lines if needed. the head office will have 4
telkom lines (via ISDN). These people do travel bookings so they'll be
on the phones a lot.


Any recommendations, pointers, etc would be highly appreciated.

If you need handsets - I have about 12 Snome voip phones for sale - they have been used but are in very good condition. You would then need someone to know what to do to connect them via the Asterix system

Thanx Kevin,

Are they cordless?

I have some corded handsets already but need the PBX part sorted.

No they are not cordless.

I am also looking for telephone advice: switchboard and 12 extensions, but we also need recording system for recording advice - so needs to be top notch system.
Any help will be gratefully appreciated.
