Just out of curiosity, does the agent continue to hear the tone in their conference until they logout and back in?
I had this randomly happen on many installations on ast 13 and never got to the bottom of it (agents would always report it AFTER logging out and back in but there was nothing of interest in the logs and it happened so infrequently in my case for the number of agents we look after, we never really put any focus on finding the cause), but it hasn't happened to my knowledge since upgrading to asterisk 16.
The DTMF tone from what I can see is coming from the carrier side, not the agent side.
Have you made some test calls yourself to see if it still happens on the calls you make in to the system? If it is, I'd be having a word with the carrier.

1) How often does this happen? Can you predict it? If so, make sure you do so when YOU are on both ends of the call to categorically remove the possibility that the Lead is pushing a button

2) jamiemuarry: Are you also on CentOS? Is your system similar to OPs?

3) What method of installation was used? If in fact you are both on CentOS, it's possible that this is an installation-specific ... feature. While I'd like to say that's not possible, I've been using Vicidial/Linux far too long to use that word. Ever since the day a client "darked" my fiber and the ISP couldn't figure out why (several days in a row, put him on his own circuit). Still don't know if the NSA was after him for something.

4) Is it possible that this is a "delayed" key press from a prior menu or other feature? Bad scripts happen.

I've been using Vicibox for all my installations for a number of years, been some time since I used CentOS.
I don't think the issue I saw is the same as the OP.
It was once in a blue moon it would happen, there would be a constant DTMF sound playing the in the meetme conference until the agent logged out and back in, and always seemed co-incided with an answer machine call if the agent hung up around the "beep" of the machine (when I think about it this only happened on UK campaigns, never US or Canadian ones although don't quote me on that).
I looked after receiving the first few reports for hours at a time in my case and tried to reproduce but never could, I gave up looking in the end and any time we received reports of it, the only advice we gave was "log out and back in when it happens". Like I say, volume of this was so low it just wasn't worth the time trying to find the cause in my case.
As mentioned above, to AFIK we haven't had a single report of this happening since upgrading all boxes to Ast 16.
