PLEASE PLEASE PLEASE IF YOU ARE A BUSINESS DO NOT GO FOR THE BT HD CLOUD VOICE PHONES!!!!!!!!! THIS IS A WARNING TO ALL FROM EXPERIENCE, WE HAVE SUFFERED AS A BUSINESS AT THE HANDS OF THESE PHONES, NO TRAINING WAS PROVIDED, EVERY SINGLE DAY WE HAVE A NEW ISSUE WITH THE PHONES, THE CALL QUALITY IS LIKE THAT OF SKYPE, CUSTOMER SERVICE IS BELOW 0. WE WERE EMAILING AND EMAILING AND EMAILING AND THEY REPLY WHEN THEY PLEASE, IF AT ALL! THEY DO NOT CARE!! WORST CUSTOMER SERVICE EVERRRRR!!! WE HAVE WASTED SO MUCH BUSINESS TIME TALKING TO BT TRYING TO RECTIFY THE ABOMINATION FOR PHONES WE HAD INSTALLED. PLEASE DONT FALL VICTIM TO THE HD CLOUD VOICE PHONES, THEY ARE HONESTLY THE WORST THING WE HAVE EVER DEALT WITH. Wait no BT customer service was the worst thing we've ever dealt with, then the phones second. We have actually been begging them for weeks now to cancel these phones and put the old ones back but every single time we make such a request the BT advisor disappears, or tries to con you into sticking with them. Just dont! 0/10
