I understand how DTMF works on SIP Trunks, what I’m not clear on is how “no supp services” would have an impact on his DTMF issue. I’m trying to understand the logic of something changing with RFC2833 or SIP NOTIFY to the point where # is now recognized, yet without changing anything related to DTMF. Wouldn’t supp services only impact the signlaing behavior of the SIP 302 message itself? But not DTMF?
