Hello,
I want to learn how calls get setup logically from caller A to caller B if there on the same PBX, when there in different offices on different PBX's, and when caller A makes an outbond call. I understand how call routing works as I created some of this I want to learn more of the nuts and bolts but at a high level overview. Does anyone have any suggestions?To expand a little bit say caller A calls B in same building on same PBX what part of the call does the PBX take care of or does the PBX just setup the call and back out from there.
Thanks,
