Asterisk+errision PBXYes, it can be done.
You will need:
1) Asterisk server
2) ATA devices ( recommended: Linksys PAP2-NA - 1 device for every two
lines connected to the PBX)
3) An appropriate amount of time to become familiar with Asterisk and the
ATA devices
You could use Cisco ATAs... but they are expensive and hard to configure... I
would recommend using Linksys PAP2-NA (ok.. so technically these are now cisco
ATAs... but we won't get into that) as they are cheap, reliable,
configurable and relatively easy to set up. A simple setup can be done for less
than $200USD if you already have a computer that you can use for the Asterisk
server. The computer can be an just abount any old computer (P2 or better) to
get started and experiment with.
Your setup would be an ATA connected to each PBX. Each ATA would register to the
Asterisk server at the main office. You will need to reconfigure each PBX to
send calls to the other two systems out through the analog line connected to the
ATA, and configure the asterisk server to send the calls to the other systems as
appropriate.
Before you start, go to the Wiki
(http://www.voip-info.org/tiki-index.php?page=Asterisk) and read... then read
some more... when you feel that you've read enough to have the basic idea of
what Asterisk is and what it does... read it again.
Organize the information you will need to design the system... This means:
1) Gather the dialplan information for all the office PBX systems. You will
need to determine a way to integrate the dialplans from all the systems so that
you can dial from one system to the others. This can be done in any number of
ways and you will have to decide on the best way to do it to meet your specific
needs
2) Gather the information you need to configure the ATA devices
3) Gather the information about the internet connections at each location.
Pay specific attention to any firewalls you will have on the network
4) plan a dialplan for the Asterisk server
5) install your chosen operation system on the computer
6) download and compile Asterisk
7) comfigure your Asterisk server. using the information gathered steps 1,
2, and 3 to guide your decisions
8) configure your ATA devices
9) test your system before you deploy the ATA devices, using a phone set to
"emulate" the pbx(s).
10) deploy the system
Good luck. 8-}

Subject: [Asterisk-Users] Asterisk+errision PBX
Dear All,
I have a setup where three errision PBX's (head office & 2 branch
offices ) are @ three different location. Head of has a errision BP250 where the
branch officers has Errision BP50's.
I wana connect all three PBX's through IP link's. My idea is to
connect BP250 ( head office ) to asterisk. This has to be done using analog
interfacing coz there is no E1 / or T1 card's on BP250 and cost is also a
concern.
Can this be done ? And what kind of analog interfaces I should use ?
For branch office sides ( Errision BP 50 ), is it possible to use some FXS
interface ( ex : Cisco ATA etc ) and connect that directly to the Errision BP
50, where the other end ( ex. Cisco ATA IP side ) connected to the Asterisk @
Head office ?
Thanks
Shahan
