Hi Support,

Does anyone know of any success story where a legacy PBX was linked to an Elastix PBX and had phones (analog) connected to the legacy PBX communicating directly to Phones (IP)connected to the Elastix PBX.

Please advise if this can be done or advise where the instructions can be found.


Thanks

Regards
Jason Morrison

Just build a trunk (using FXO's) between the Elastix box and the Legacy PBX, make sure the context is from-internal and design your dialplan to suite extension dialing, you can also use FXS ports as internal extensions on the PBX, but then outbound dialing through Elsastix is limited by your skill and the PBX's abilities to route calls , Examples can be found all over these fora.

I have about 20 extensions, on the legacy PBX to communicate across to IP extension and therefore was planning to use a T1 interface between PBX's.

Can this substitute for FXOs/FXSs ??

You are attempting something quite ambitious, it would behoove you to be more familiar with telephony in general and Asterisk in particular, had you searched the fora, you would already have your answer.

The search box at the top of this page?, http://voip-info.org ? http://www.google.com ?

For a T1 you will need

A ) your wiring right.
B ) Your line build-out right.
C ) Your rx/tx gains right
D ) Your clock source right
E ) Your Framing right
F ) your line encoding right
G ) Your line signaling right,
H ) Your line provisioning right
I ) Your trunk provisioning
J ) your dialplan right.

You will have to that on both the Elastix Box and your Legacy PBX.

I would point out that from your first post . . .Hi Support, . . that this is a forum where we share, not a support line, there is a "paid support" link at the top of this page if this also sounds too daunting where the engineers at Palosanto will help you more directly.
