DESC: Whether it's a fashion statement, a big-button phone or a communication tool for your home business, Sony's got the perfect phone for every room. This phone's 4-line operation accesses four incoming lines from a single telephone (subscription to four separate lines from your telephone company is necessary). JOG DIAL control allows one-finger access to directory dialing numbers and Caller ID memories; simply push the button and jog up and down to find the entry you're looking for; then push the button again to dial the number! Caller ID with Call Waiting allows you to screen the phone number and name of an incoming second call while you talk on the first. Visual Message Waiting indicator lets you know when you have a message waiting in your voice mail via red LED.
