Hi all, I have a problem with the Snom m9 dect phone’s (playmobil model). I configured 2 bases, 1 with 3 m9 phones and 1 with 4 m9 phones, I putted all the phones into a ring group. I also putted 3 snom 320 phones in this ring group. When there is a new call, all the phones in the ring group suppose to ring. The snom 320 always rings, but the little m9 phone rings only when they feel like it. Anyone got a suggestion? The dect phones are all in range of the base station and they have no problem making a call.
