Phone System Management Does Not Load

Hi,

I've been trying to access the Phone System Management option for the last 2 hours, and it just shows the loading icon next to the menu option and nothing happens.

I have tried it from two different accounts and different browsers as well, but still nothing. The Chatbot was unable to be of any help.

There is an urgent setup that needs to be done, but it's being delayed due to not being able to access the menu.

Would appreciate if this is rectified.
