The Record-a-Call feature is available only on PARTNER ACS Release 3.0 or later. PARTNER Messaging must be a 4-port or 6-port system and the user must have a system telephone. The Record-a-Call button allows the user to begin recording a call in progress with one touch of a button. (If the system detects 15 seconds of silence after recording has begun, the system automatically turns off the Record-a-Call feature, and the user must press the programmed feature button to resume recording the conversation. The new recording will be saved as a separate message.) The recorded conversation is saved in the user's mailbox. The button programmed for this purpose must have lights.
