Always remember to connect the power supply last!

If by chance, you should experience any calling issues,

simply unplug the power supply to your phone adapter,

wait 5 seconds, then plug power back in. Allow the adapter

to re-boot for a minute.

This "power cycle" usually fixes any calling issues.
