I don't know how long this has been going on but we can call everywhere using the cordless phone attached to the Obi200 configured with GV and can receive calls from Skype and mobile phones but evidently not from AT&T POTS lines. Those callers are routed directly to Google voicemail.
Since most discussions are around no incoming calls of any kind, I'm wondering if anyone has any ideas on possible remedies for this narrower problem.
Thanks.
