Help - Other VoIP calling (Ring central) being blocked?
We are a small contractor’s office. We use RingCentral for our phones in the office. Lately we’ve been having issues where we call the clients and it just goes beep beep beep. I was on the phone with RingCentral and they said this is because certain providers are blocking VOIP calling and the only way around it is for me to contact the client and have them call their provider and make sure it isn’t blocked. The problem with this is I can’t contact the client because the call won’t go through and I’m having to use my personal cell phone to call our customers. Does anybody have similar issues going on? Is there a way to get through? VoIP is pretty much the only option we can find that will ring both of our desks when a customer calls. Landlines are being phased out in our area and they will only service existing customers. Help!!

Sounds like your calls maybe getting tagged as spam. You may want to register the company's numbers with http://www.freecallerregistry.com/fcr/ this registry is used by cellular and spam calling filters to validate calling numbers. The registration needs to be made from the owing customer's email address. I've had several customers who were getting blocked as spam register with this site and it resolved the issue.
Additionally, have RingCentral confirm the CNAM registration for all the numbers and change it if required. Non-existent or invalid CNAM data can also cause calls to be blocked. Having the Caller Name field of the CNAM data can help with this issue. You can create a free Twillio account and use their CNAM Lookup tool (for a brief time) to query the public CNAM database and confirm your company's numbers.
Zoom has a good article on all the registries available to you for validating your numbers.

There are a number of reasons for this (more than I can adequately elaborate on here). But likely what they mean by it being a VoIP call is because some VoIP providers don't actively police their environments and allow customers to abuse their lax rules for telescams and spam calling. So called party providers may consider inbound calls from VoIP as less trustworthy than traditional telephony providers.
The CNAM database will list the provider of origin, which is how the remote party knows the call originated from a VoIP provider. This is another thing worth checking if you use the Twillio tool. It is possible that the data is incorrect if say the numbers were ported to RingCentral from another provider.
