Hi, I am looking for a solution for the feature "Distinctive Ringing By DN" on IP Phones (1140 and Spectralink 2210). I have several sets (mixed of 1140 and 2210) that would required to have a "distinctive ring" when they received call from some DNs. Is there another solution since the feature "Distinctive Ringing By DN" works only with Meridian sets (M2006, M2008, M2008HF, M2616, M2016, M2216, M2317). Thank you!
