Hi, we have a strange issue with our 10 Aastra 6757i. Some of them have the 3CX company phonebook and the others haven't. And today, we add an entry in the 3CX company phonebook but it's not visible in the Aastra phonebook. All the phones have the same firmware, the same configuration server and they have an extension in 3CX... So, what's wrong with our configuration ? Any idea ? Thanks in advance !
