Our takeaway store has changed since BT Cloud voice contract, use their assigned numbers phone service, Then our landline was cancelled without notice when we signed up before If I go back, I will lose our appeal, which is to use this Cloud system, so there is no way to replace it, change the phone and change it No., then we order the system phone call manager before Can display customer information when calling, mainly to connect the phone line , now our contract is network, there is no telephone line, so also Unable to link call management, customer information cannot be placed on the computer The system shows that it must be copied by hand. I contacted the installation order department. Traditional engineers, they said to find BT, BT said they couldn't do anything Help, so I don't know if I know how to do it. thanks
