Hi, I’m trying to call my ISP. I have to press 9 for English. It has worked fine in the past but it is not working correctly from the laptop or phone. If I call the ISP from another app then DTMF works fine, the third party app has a usage limit so I can’t use that.
The weird part is if I call a DTMF tester 631-791-8378 from firertc then the DTMF works.
What is going on?
