Minimal restrictions

We bought this phone for our defective T-Sinus 720 PA, which supplied two handsets (T-Sinus 702 and 700K). We were careful in previous pairings from different base stations and handsets as we had restrictions on the connection. SO worked eg not the caller ID function.
That's no problem with this phone. The handsets could be connected without difficulty and the number transfer works. Operation is simple and the display clearly on both the base station and on the handset.
A few not too important limitations we suffered yet:
Phone number could not be transferred from the old handsets. Similarly, one can between the advertised here two phones the phone books do not "upgrade" as it is known from Siemens phones. One can only transfer individual numbers or the entire directory when it can delete previously on the target phone.
In addition, the ring tone is a bit quieter than the Sinus 720PA, but as with us anyway in almost every room, a telephone rings when someone calls from the outside, that's yet to be absorbed.

All in all, we have not regretted the purchase.
