Hi Lt!
Thanks for the links. It's hard to know when individual users' issues have the same root cause, as there are various problems that can present similar symptoms. But, I agree that something seems to be intermittently failing. I experienced this myself a couple hours ago, but I figured it was a one-off glitch.
Some of the GV team is in off-site meetings today and tomorrow, but I assume they'll notice the posts and investigate it. See my comments below, and append the thread you started with more details (date, time/timezone, last 4 digits of your GV number and last 4 digits of the number calling your GV number and the forwarding phone number).
With regard to the DTMF issue, that's probably something unrelated. We see this occasionally. It's either caused by someone trying to verify a VoIP number, and their SIP client isn't configured properly to match the DTMF method supported by their SIP carrier, or, it's an issue with one of the carriers between you and GV. If you're using a SIP carrier, you can try toggling the DTMF setting on your OBi:
Service Providers --> ITSP Profile <x> General --> DTMFMethod <-- Start with the default, "Auto", and if that doesn't work, try "RFC2833", and then try "InBand". Also, make sure you are using the G.711 CODECs as the first choices.
If your CODEC settings don't fix it, and/or if the phone is a mobile, not a VoIP line, then open a dedicated discussion thread on the GV forum. They'll need a redacted screenshot of your GV Settings page, Phones tab, with only the last 4 digits of your telephone numbers visible and the rest blocked out for privacy. Also, you'll need to post some recent examples (timestamped) of the failures, so the engineer can look at which carrier was handling the calls.
