Hello. Thanks for the reply. I believe you're referring to regular "Phone" mode where *99 is dialed for PTT? I am using Vox mode so that my mute button essentially becomes PTT. I did try using phone mode yesterday in case a change was made that affected DTMF in vox mode.
My dialplan commands are as such:
exten => 1234,n,Rpt(${EXTEN},Pv)
