None of my previously working dialing strings (access codes, passcodes, wait and pauses) seem to work since I enabled "Advanced Calling" (VoLTE) on my line... same phone on which these worked before... Do extended dialing strings not work because the receiving side is listening for DTMF commands that are not supported on the packeted VoLTE network?
Good question. It's likely due to Advanced Calling that these dialing strings no longer work. What model phone do you have? I can take a closer look into this.
