I have a ring group, 850. Ring group 850 has four extensions in it. What I dial that ring group, two of the four extensions show the callerID correctly (caller ID prefix is set in the ring group). The other two extensions don’t show the prefix.
Same model of phones (yealink), same firmware, same templates on the phones.
