Control data exchange of cordless telephones
Recently, I switched to another telephony provider. Until then, I had a common connection and operated my cordless phones over a PBX.
After the change and after registration of all phones to the "Fritzbox (VoIP)" I had to realize that a transfer of phone book entries from one phone to another, was no longer possible.
So I was forced to enter all the numbers in two newly added phones, by hand.
Fortunately, I had not disposed of the old PBX (had been in use for over 15 years). So just the system to the network, phones activated again there or re-registered, and lo and behold, everything went as before.
Phone lists were easily transferred. Then the handsets again activated on the "Fritzbox". So it is probably better to think carefully about what you can dispose of, and what you better still retains.
