Re: Dtmf over rj45

Are you talking about embedding this sort of functional noise into a line
being used by ethernet? and yes most quality switches would try to clean up
the noise in order to secure the data unless it just created enough of an
interruption to just disrupt the connection as a whole.

RJ45 is a socket type so you can wire it to do whatever you want. you can
use cat 4,5,6 cable to transport anything you want. I know multiple sites
that wired ethernet cable for POTS just because it gave them the ability to
do a number of things based on need.
