I have a situation where when you first turn on a wifi phone it registers, everything works great, and at some point the phone is no longer registered.
The issue is when a call comes in the phone won’t get the invite since it’s not registered, if you power cycle the whole thing goes through the same process.
Are there any additional criteria I need to add to the device in order to maintain it’s connection?
Using current FreePBX & EPM.
I have the grandstream WP810, but utilizing grandstream WP715 as a template.
