Wondering if there's someone on from Spectrum on who can point me in the right direction for a DTMF issue. Normal Spectrum trouble tickets don't seem to be working.

We have a customer with several analog lines that's not getting DTMF tones, so calls are hitting the IVR and not able to go anywhere. It doesn't happen with all carriers -- AT&T and Spectrum work. Calls that traverse the Verizon network do not.

We have a temp fix in place (CSR answering calls that fail the IVR) but it's been going on for a while now and we need to find a more permanent solution.

Thanks

Shawn
