I have purchased a SPA500s Expansion Module for a SPA 504G handset, but there appears to be an issue with the extension lights
I have 5 extensions provisioned on expansion unit via the hosted control panel, but the lights appear intermittently.
1. No lights appear
2. Then 30 minutes later 1 light appear
3. Then 30 minutes later a second green light appear (2 green lights now showing)
4. 1 hour later, a 3rd green light appear (3 green lights showing)
5. 30 minutes later, all lights go off.
6. Then the steps repeat (1 green light)
When the green lights appear, they do work (i.e red when used, green when idle)
The service provider has confirmed it is showing as provisioned correctly on their system
I have also checked all connections.
Please could anyone solve this strange issue for me.
