I have just acquired additional 20 SIP-phone activation licenses on top of the 40 I already had. On the Activation key page it is showing that the activation of 60 SIP-phones have been activated but I am only able to register 30 handsets only. The rest either show FAULT/OUS and any that might attempt to register manually the responds is ACTIVATION OVER-LIMIT.
How do I get around this challenge if any have encountered a similar case? I have tried system reboot to no avail.

Check system capacity license. You may only have 30 user/ system capacity
