Configure Hotline (PLAR) on Cisco MPP, ATA19x, Cisco VG4xx ATAs, and Audiocodes ATA devices
As a customer administrator, you can configure a phone to automatically call a pre-defined number as soon as it goes off-hook. This feature provides the benefit of speed and convenience. The Private Line Automatic Ringdown (PLAR) feature is a hotline configured in Control Hub and is applicable to ATAs, desk phones, users, and workspaces.
Once PLAR is configured on a line, E911 dialing no longer works from that line. Phones set up with the PLAR feature can’t dial any other numbers from the line that is configured for PLAR.
