Any workaround? I suppose I am not the only one who prefers not to receive group calls on the mobile also because on the phone you cannot tell if it is a direct call or a group call.
You could send the name of the ring group, even a couple of letters/ letter & number, to keep the entire name short. then you'd know if it was a direct call, or a ring group call.
You are going to be adding a name, before or after the caller ID name as sent by your provider (your choice). If the originators name sent is long, then the ring group name you choose, or part of the existing name may be partially "pushed off your display". Try a short one first and see how it works.
