Extension busy

[andresilva]

I have a UC540 with seven ip phones 6921 and two 7962.

Is there any way of knowing that one extension is busy, on the ip phone 6921?

For example, I make a call from my extension A ( ip phone 6921) to extension B ( ip phone 6921), and extension B is busy. Is it possible to know before making a call, that extension B is busy?

Thanks,

Andre

Hi Andre

Yes you can watch other extension from other phone, using BLF to Determine a Line State.

This feature provides a visible line status indicating whether or not the line is in use. A monitor-line lamp is off or unlit only when its line is in the idle call state. The idle state occurs before a call is made and after a call is completed. For all other call states, the monitor line lamp is lit. A receptionist who monitors the line can see that it is in use and can decide not to send additional calls to that extension, assuming that other transfer and forwarding options are available.

Basically you want to configure a watch or monitor line on the CME.

ephone-dn 1

     number 1000

ephone 2

     button 1w1

This would configure a button on ephone 2, that watch the status for the ephone-dn 1000
