I have Google Voice calls forwarded to a Verizon cell phone (previously AT&T). We had conditional call forwarding set up and working on the AT&T cell phone, and again when we switched to Verizon several weeks ago. As of today, we discovered that the Verizon conditional call forwarding is no longer working.
We have turned off/re-enabled conditional call forwarding multiple times and to multiple numbers (Google Voice and regular cell phone lines). We confirmed that total call forwarding works. We are using *71 for conditional, *72 for total, and *73 to reset.
We've reported it through the Voice app, and raised an issue on the Google Voice support forums. Hoping someone has some ideas here.
The Google Voice line is a health care provider line--calls need to be forwarded back to the provider voicemail.
