NTT has been testing the service since January 28 in the Yokohama, Nagoya, and Fukuoka area codes. Nationwide commercial service is expected to begin in October. Many consumer electronics manufacturers have this month announced telephones that take advantage of the new services.
All models are cordless.
The IS-W767EX comes with an extension telephone, which also has an LCD display. Kenwood also offers a function for consumers who do not have a contract with NTT for Caller ID service. This function intercepts all incoming calls, prompts the caller to enter his or her phone number, and then offers the recipient the option of whether or not to pick up the phone. This has proven so popular a feature that Sony now includes it on its telephones for the home. Nanotteru's answering machine uses flash memory to record incoming messages, meaning there is no waiting time when replaying messages, as there is no tape to rewind.
