An optometrist | opticians paging system from Dinggly brings many advantages over traditional systems via it’s cloud architecture. When call buttons are pressed, optoms will see, from it’s LED turning green, that somebody is on their way. Call buttons can send up to 4 messages. Alternatively, tablet calling allows many call types plus text messaging (frequently used messages can be pre-loaded) and can receive discrete messages too, such as the next customer arriving late.
