I have a service request open with Sonic support, but I was advised to also post here in case anyone may have run across this.
Recently, DTMF has stopped working on inbound calls. Here is what I've found:
- If I use the house phone and call my AT&T cell phone, answer the call, then press digits on my AT&T cell phone, I hear them on my house line.
- If I use my AT&T cell phone and call my house phone, answer the call, then press digits on my AT&T cell phone, I DON'T hear them on my house line. I hear a bit of a "click". That's it.
I have also tried this with another external provider (Verizon wireless), same results.
I have a straight run from the MPOE to my office, so the line I'm using is dedicated and not split throughout the house, and I ran the line just a few years ago, so it should be in excellent shape, but my next thing to try is to plug it into the line at the MPOE, in case something may be up with the house wiring.
I suspect inbound calls and outbound calls are being routed through different equipment or configurations at the local CO, but I want to exhaust any other possibilities. Anyone happen to have run across anything like this?
Thanks in advance for any help,
