Have them complain that they can't reach a known working number.
The problem is in Verizon's routing tables.

I am sure you are a busy person but I have had an ongoing problem since last Friday and I am getting nowhere with Ooma tech support or Verizon tech support. Since Friday 8/9/19 I am unable to get calls from any Verizon customers in the 609 area code. They claim that all they get is a Fast Busy Signal. When learning about this I naturally called Ooma tech support and was told by a non-english speaking person “Oh yeah, Verizon is down” and she immediately hung up on me. I waited 48 hours and was informed by several more Verizon customers that they can not reach me. I called back Ooma and was told the problem is not on their end and that I had to call Verizon and report a “Routing” problem. So I called Verizon and they would not talk to me at all because I am not a Verizon customer. So I emailed “Hans Vestberg” CEO of Verizon and got an email from Verizon Executive care team and I provided them 3 examples of numbers who were getting a fast busy signal when calling me. The numbers were provided to them. I waited another 24 hours and the problem still persisted. I emailed Verizon Executive Care Team back today and they informed me they ran multiple tests and that there were not problems in their network, switches or routing and that the issue lies with the VOIP provider ( Ooma). I called Ooma back today and spoke to Angie ( again, broken English). She said she sent some type of signal to my Telo and she wanted me to get off the line I was speaking to her on and have a few Verizon people call me. She said she would call me back. Well, the Verizon customers were still getting Fast Busy Signals and Angie never called back. So as of now, No Verizon Customers can reach me, Verizon is claiming it’s not them and Ooma is claiming it’s not them.
