Att phones all over cannot call ring central lines

Hi there @Richmarino75, we're here to look into what's going on with regarding calling businesses that use RingCentral. 

We'd like more context about what you're experiencing, as so we can look into our options for making this right. Please answer the following questions for us:

• Is this for a business account, or are you reaching out for an impacted business? We want to know if this is something that you're currently experiencing, or if you're looking for a resolution for your customers that have AT&T. This'll determine what needs to be done next. 
• Are you experiencing this with a personal service account? If so, we'd have a few follow up questions to get a better idea of the scope and what troubleshooting you've tried:
  • Have you rebooted your phone, as mentioned above? This refreshes your device's connection, which may be the cause. 
  • Are you getting any error codes when you call, or does it just fail to connect? This extra info let's us search for potential causes and troubleshooting steps. 
  • What is the make and model of your device? We'll be able to try more specific troubleshooting with this information.

Please share this information with us, so we can determine what needs to be done regarding this issue.

This is an ongoing issue that happens every few weeks between RingCentral & AT&T wireless callers.

Both support says it's not them. 

Seems like this has been an issue for many years according to some of these posts. 

It seems like this is happening again. We use RingCentral and are having reports that ATT&T wireless customers are getting a busy signal when trying to call in. Is there something that can be done to resolve this? It is causing a pretty serious disruption to our business. 

Hi, hopefully AT&T will do something about this. It happens about once a month we probably lose $10-$15,000 every time it happens.
