Re: Passing Caller ID through non-CID aware PBX?

["wkearney99" <wkearney99@xxxxxxxxxxx>]

It might be better to ask this in a telco or pbx forum.  Do those phones
have a display on them?  Or at you talking about trying to push the signal
to standalone CID units inline with them?  Unless those phones and that PBX
are designed to allow something to "inject" that data it's not going to
work.  That and most PBX systems don't document those kinds of inner
workings.
