Hello,
Recently we've discovered that DTMF tones on external calls are sent from an endpoint in our system are short and "poor quality" and tend to double up like you pressed the button twice.
We've tested multiple phones and ATAs and it doesn't seem to change. Internal tones seem to work just fine.
We've searched and tried a few things but anything tried hasn't helped. Any suggestions appreciated.
We tried changing DTMF modes on the ATAs with no real change in the behavior.
What it appears to do is the system is getting the DTMF signal from the endpoint, Fusion recieves it and then spits it back out, but I think the end user is hearing both.
Below are some logs when pressing a few digits if it helps.
Any suggestions? Thanks much!
