I forgot something to mention, sorry, the number Problem that i write here are only on Reception-Desk, phone.
The Reception has Register two Nr. “Personal/Company Central Nr.” on his Phone. If the Reception will pickup any internal Call, she don’t see the external Phone Nr. She see only the internal Nr that had picked up.
all other Phones are running correct. After check the Individual Settings from the phone i don’t see here any differenses. Also Firmware are the same.
