Pairing a Snom C52 to a VTech VCS752

Quick video demonstrating how our VTech and Snom conference phones are cross compatible allowing you to register our Snom C52 wireless expansion speakerphone to our VTech VCS752 conference phone.
NOTE: Our Snom C52 supports DECT auto registration out of the box, if you are not using auto registration and you may need to hold the Mute All button for 5 seconds to disable DECT auto registration before you can manually register as seen in this video

My C52 keeps leaving registration mode as soon as I let off the registration button. Any tips?
