Phones - Why do all of my phones report that they failed to contact the proxy server?

If all of your telephones report an on-screen message that indicates they've failed to contact the proxy server, you may be affected by one of the following conditions:

1. The current date may be on or after May 28, 2021 and

   1. your Switchvox may be of 7.x version less than 7.6.2

   2. your Switchvox may be of 6.x version less than 6.8

   3. your Switchvox may be of 5.x version less than 5.12

2. Your Switchvox system may not be running

3. The network connectivity between your telephones and your Switchvox may be broken

   1. Your internet or Internet connection may be down

   2. Your Switchvox may have responded to improper passwords by actively blocking connections from your network location

If the first condition is true, visit the Server->Updates page in your Switchvox Admin Web portal and update to the latest version.
If the second condition is true, power on your Switchvox system.
If the third condition is true, check the status of your network connectivity to your Switchvox and/or the status of any IP Blocks by visiting the Server->Blocked IPs page in the Switchvox Admin Web portal.
