<p>It is not a very straight forward procedure. First of all you need to decide how you would make the two PBXs communicate with each other. I am sure the old PBX doesn't support VoIP ptotocols. Can you use T1 or E1 to make them communicate with Asterisk? Once the calls are successfully sent from the old PBX to asterisk, rest just requires a good dialplan on asterisk. But if you are new to asterisk, it'll be not easy either.</p>
<p>Why not just get rid of the old PBX and receive calls straight on asterisk?<br></p>
