Aastra 55i and Trixbox – Call Pickup / BLF

In the previous post here we looked at getting Endpoint Manager in Trixbox working with a couple of Aastra phones.

In this series of posts I’m going to look at some different scenarios and programming the softkeys.

For my test setup I have the following configured –

x1001 – Boss
x1002 – Secretary
Inbound UK DDI which is routed to the Boss’s extension 1001

We want our secretary to be able to monitor the Boss’s phone. Call the boss quickly, and pick up the phone if it is ringing. For this we can use a feature called BLF (Busy Lamp Field). This will give us an icon on the handset showing if the boss is on a call, or their extension is ringing.

To do this we need to do a couple of things. Firstly we need to tell the handsets that we allow directed call pickup. We can set this in the main Aastra phone configuration file /etc/tftpboot/aastra.cfg. So edit this file and add the following 2 lines to the end –

directed call pickup: 1
directed call pickup prefix: **

Next we go in to Endpoint Manager on Trixbox and assign a soft key to monitor x1001. So go to Endpoint Manager and click the MAC address for x1002 (the secretaries phone) –

Now we’re going to set the Name for softkey2 to “Boss”  (softkey1 is used for voicemail by default and if you set it here you will overwrite that configuration), set the Mode to ‘blf’ and set  Data to be the Boss’s extension (1001) –

Now click on Update at the bottom of the screen and then restart extension 1002. There is a menu option on the handset to restart the phone.

Once it restarts you should have a key labelled ‘Boss’ that you can press to call the Boss –

and when the boss’s extensions is ringing the LED will flash and there will be a bell symbol next to the extension number. You can pick up the call by pressing the button next to the bell symbol –
