Expandable to include up to 8 handsets, the Motorola  MD791 cordless system is a good option for large households.

Included are one corded desktop phone and a cordless handset with a charging station. The handset uses the 5.8GHz frequency, so you don't have to worry about interference with Wi-Fi networks. The range is quite good and call quality is better than average.

The shared phonebooks hold up to 50 entries, while the call waiting/caller ID log contains the information from recently received calls. Meanwhile, the digital answering machine stores up to 15 minutes of messages that can be checked from either extension. Other features include: distinctive ring tones, emergency battery backup (batteries are sold separately), intercom, last-5-number redial, and speakerphones on the handset and the base station.

If you're looking for some versatility and can benefit from multiple handsets, the Motorola  MD791 cordless system is a good choice.
