UK's Ofcom new ruling - Will it impact UK customers?

I have just read an article in the BBC this morning mentioning that all VoIP calls that originate from outside the UK will now be blocked.

Seeing as RingCentral makes use of VoIP technology I wanted to know if this will impact RingCentral customers that are based in the UK. Specifically, I'd like to know:

• Is something being done by RingCentral to make sure that all calls we make will continue to work as they currently do?
• Are there any changes that our company needs to do to ensure that we can still make calls going forward when this new update occurs?
• What will happen to a call if it gets redirected to a RingCentral server based outside of the UK?
