UC320 BLF Keys



I am having the following issues with a UC320W and SPA508G phones.

I am unable to configure BLF keys on the SPA508G phones, there is no option in the configuration only speed dials or monitor, although the documentation shows the option for a BLF key?

When in a call none of the programable button labels are visible so it is not possible to xfer using the speed dial keys, this renders all the programmable buttons pretty useless?

ANy ideas appreciated

Hi Mike,

Line monitor button is the same as BLF, just a different name. You can configure Line Monitor button to monitor another line and blind transfer a call to this line. The following is the detail description about Line Monitor button:

Line Monitor: Monitors the status (ringing, on a call, or on hold) of a single extension. Also known as Busy Lamp Field (BLF). It also functions as a Auto-dial (Speed Dial) button to immediately call a user or to immediately transfer a call to a user, without consultation. In addition, it can be used as an Individual Pickup button to pick up a call that is ringing on the specified extension. If multiple calls are ringing, the first received call is picked up. A device can have only one Line Monitor or Phone Monitor to monitor a user. Tip: This feature is useful for an administrative assistant who monitors an extension of an executive, and for co-workers who back up one another during breaks. Note:  This button does not reflect the user's activity on other extensions such as Shared Lines and Shared Extensions.

Best regards,

Wendy Yang
