We've had several reports of issues so there is a possibility that there is something going on, but everything is fine on our end as far as we can tell. We are not able to replicate any issues and there are thousands of calls going on right now. It could have been a temporary network blip somewhere along the way which is why isolated. We're still checking over everything, but no issues are known on our end at this time. If you are experiencing issues, please contact support@voipo.com for assistance.
