[Asterisk-Users] Re: Intergrate Asterisk IP PBX with Legacy PBX, continuing existing funtionality of legacy pbx

[Steven]

We did this type of integration.

What I did to make it easier was to get new DIDs for the asterisk extensions. (no really new, they were from a building we were 
closing)

We put in a multi PRI card in the asterisk.
DID 56XX stayed in asterisk.
DID 51XX was passed to the legacy PBX via:
 exten => _51XX,1,Macro(dialout-trunk,2,${EXTEN},,)   ;we used to use Dial, but have switched over to freePBX for admin and use 
their built in macro.

I was able to turn on a prefix of  "9" for outbound Legacy calls, so calls are read by asterisk with just 1 set of rules.
I did have to add
exten => _956XX,1,Goto(ext-local,${EXTEN:1},1)  ; to make those legacy PBX calls get to an asterisk extension.

Before figuring out the "9" prefix on the Legacy PBX, we just did the opposite, but it was more work because I had to add a normal 
route and one without a 9 for each VOIP provider, etc.

I did have to alter the Legacy PBX to allow the 56XX number to go out a trunk.

Hi All,

I would like to explain the layout that i am trying to achive. I am so
helpless on this regard.

So here is the story ........

" This is with regard to the setup which you can find at the

"Asterisk The Future of Telephony" , chapter 11, page # 196-197, I am
attaching the picture for your information.

Now I am taking a challenging step to of integrate IP PBX with our
Conventional PABX system.

*Existing Setup over view*

Our existing includes traditional Pabx, E1 Line from telecom provider,
16 direct lines another telecom provider. there are around 120 extensions.
E1 Link using for DID and 16 lines using for as hunting group.

*New Integration.*

"Integrate asterisk ip PBX with legacy Pabx which continues
functionality of the existing setup"

I am planning to install 2 E1 cards in Asterisk box. Remove E1 link from
legacy Pabx and fix it to 1 E1 card and other E1 card will using
to connect traditional PABX.

All previous DID's which configured with the traditional PABX will be
configured in asterisk.

Actually I am not sure that i will be able to achive this migration ,
but i am trying to acomplish.

It is very much appreciate that if anyone can guide me on this regard.

Thanks & Regards,
Vidura Senadeera.

Sri Lanka.
