Disable dial tone after call ends

Why would anyone want to listen to a dial tone or a fast busy (reorder) tone? I can think of better things to listen to.
Take Steve's advice and just hang up.
I think the answer is pretty obvious. His African Grey Parrot, which could perfectly mimic DTMF tones, was placing random calls to her home country (Congo) whenever the speakerphone was off-hook with a dial tone.

Thank you all for your warm welcome to the forum. I'm sorry that my purely technical question was so personally upsetting to some of you. ???
Sorry about that. In their way, I'm pretty sure they were trying to be helpful. Quite often, it seems, people ask questions that require some clarification. To the point, I guess, where some of our more senior/experienced members don't always feel they should answer the simple question that was actually asked.
I do hope you'll stick around, though. You clearly seem technically minded and could probably help others.
If I had to guess why you were asking about suppressing a secondary dial tone, I would wonder if it had something to do with your screen name.

I believe it is not possible for a single undoctored human or animal voice to emulate Dual Tone Multi Frequency.

So what you're saying is I need two parrots to pull this off...

I do have a pay phone hooked up to my Obi (personal, just as a hobby not for business use) and yes, by having a dial tone after the other party hangs up it would allow someone to bypass the phone's security and allow for additional calls to be placed without the phone being able to enforce it's dial restrictions. For some reason the phone's "anti-fraud" setting doesn't detect the second dial tone and interrupt it like it's supposed to. Nobody is making pay phone boards anymore so I doubt the manufacturer will have any firmware updates to fix this :) And not that it matters for personal use, but I figured I might as well make it authentic, since it was probably just a setting somewhere on the Obi (which it was).
Also, from what I recall from the olden days of actually having a "real" land line, my provider never provided a dial tone after the other party hung up, so it was just weird/unexpected behavior to me. And there's been a few automated systems that I've called in to that drop the call unexpectedly, and I'd rather know this by hearing a busy tone vs. a dial tone blasting into my ear.
