Aastra 430 successor

Hello everyone

A customer currently has an Aastra 430 in operation, to which 4x desk telephones are connected and 2x DECT base stations to which 4x DECT telephones are then connected

Currently everything is simply connected with an analog telephone cable, but there is actually a LAN route to all telephone and DECT base station locations

Now the customer wants a follow-up solution because the part is EoL, what good products are there?

What is particularly important is the seamless collaboration of the DECT telephones and desk telephones and that DECT Multicell because the 2 DECT base stations are in different buildings (there is a LAN connection between the buildings, so a successor solution that is IP-based would be possible without any problems )

The customer actually doesn’t want a hosted PBX but rather what the onsite is again
