Thought you might.

I can't imagine this is a data burst of any kind since several people have made this work with simple adapter harnesses,
I think that the adapter harness don't use the OEM input, they just mute the radio then overlay the phones output to the front speakers directly.

so I sort of think it must operate off the same pull to ground that activates the mute. but that's a pretty lame guess. harmless to try though, I suppose.
Indeed, If you have a DVM then attach one of the probes to the "tel-on" wire and see what happens, I shouldn't think it will do any harm, ie pulling the wire to ground, like you say worth a try.
