MONITORING ANALOG LINES

The UCM6XXX supports SLA (Shared Line Appearance) that allows mapping the key with LED on a multi-line
phone to different external lines. When there is an incoming call and the phone starts to ring, the LED on the
key will flash in red and the call can be picked up by pressing this key. This allows users to know if the line is
occupied or not. The SLA function on the UCM6XXX is similar to BLF but SLA is used to monitor external line
i.e., analog trunk on the UCM6XXX. Users could configure the phone with BLF mode on the MPK to monitor
the analog trunk status or press the line key pick up call from the analog trunk on the UCM6XXX.

Enabling SLA Mode

1. Enable SLA Mode under the Analog Trunk Parameters.
2. User can check Barge Allowed if needed in order to allow barging into a call in progress from SLA
stations by pressing the configured line button.
3. Hold Access is used in order to allow any station to make the line on Hold, and any other station can
resume it if it is set to Open, or restrict only that station that placed the line on hold to resume it by
setting the option to Private.
Note: SLA mode is supported on trunks with one PSTN line only. When using SLA mode, the trunk will be
dedicated to SLA stations for incoming and outgoing calls bypassing configured inbound/outbound routes.

Create/Edit SLA Station

After enabling SLA Mode under the analog Trunk, SLA Station can now be configured on web GUIExtension
/ TrunkSLA Station.
