Dear Rey,

The answer is yes, on one obvious condition:

The jack is connected to the PBX on the other end in such way that the PBX extension port is connected to pair #1 (blue/white-blue).

This is, of course, assuming the PBX can talk to this particular type of phone (proprietary feature phone vs. analog).
