Panasonic's KX-TG6700B two-line expandable phone system gives you all the call-managing options you need for your growing household or small business. The base unit comes with a single cordless handset, and you can add up to seven more cordless handsets for additional rooms.

The handset and base both have their own keypads, as well as built-in speakerphones for added convenience. The digital answering system holds up to an hour of messages, and the 50-entry directory gives you easy access to your frequently dialed numbers. You can even do four-way conferencing between two handsets and both of the outside lines.

Should I get a 2.4 GHz or a 5.8 GHz phone?
Both 2.4 GHz and 5.8 GHz phones give you clear reception and plenty of wireless range for most homes and small businesses. However, if you have a Wi-Fi® computer network on the premises, then a 2.4 GHz phone can interfere with your PC's connection because it operates in the same frequency range. A 5.8 GHz phone uses a higher frequency range to avoid this interference, making it a better choice for folks with wireless networks.

Answering System Features

Total Recording Time: The total time for recording is approximately 60 minutes for all messages. The unit will announce when the remaining recording time is less than 10 minutes. A maximum of 99 messages can be recorded. Messages and greetings are stored in flash memory and will not be affected by power failures. All messages are saved until you delete them. A small LCD on the base unit indicates the number of recorded messages.

Caller's Recording Time: You can select from 1 minute, 2 minutes, or 3 minutes for recording incoming messages, or Greeting Only which records no message. Each line is set independently so the times can be different for line one and line two. Individual messages can be played back and erased from the base unit or the handset.

Greetings: You can record personal greetings of up to 2 minutes. Each line can have a unique greeting, or both can share the same greeting. The unit also comes with 2 pre-recorded messages; one used when the unit is set to Greeting Only or has no available recording time, and one used when a message will be recorded.

Number of Rings: You can set the number of rings before the answering system answers the call. The settings are individual for the two line, so they can be different. Your choices are 2 to 7 rings, or Toll Saver. When set to Toll Saver, the unit will answer on the second ring when there is at least one new message, or on the fourth ring when there are no new messages. This allows you to save on toll charges when calling to check your messages by hanging up when you hear the third ring, knowing there are no messages.
