Using Busy Lamp Fields, Call Pickup, and Speed Dial on Linksys Phones With trixbox

Contrary to the instructions previously posted in the trixbox forums or in Linksys' own official documentation, this is how to make BLF (Busy Lamp Field), CP (Call Pickup), and SD (Speed Dial) work with trixbox.  We are currently using version 2.6.1, but these instructions would theoretically work on anything using asterisk 1.4.

• Update to the latest firmware (6.1.3 minimum) from linksys.com.
• For SPA962 - Access the phone’s GUI and go to Admin – Advanced then to the SPA932 tab.
  • Change Server Type to Asterisk.
  • Change SPA932 Call Pickup Code to *8 (Must also setup all extensions to the same call group in FreePBX).

•  For SPA942 - Access the phone’s GUI and go to the Admin – Advanced then to the Phone tab.
  • Scroll down and look for Line Key Extended Function under the Line Key 4 section 
  • Change Server Type to Asterisk.
  • Change SPA932 Call Pickup Code to *8 (Must also setup all extensions to the same call group in FreePBX).

• Go to the Phone tab.
  • Change the Extension to Disabled.
  • Enter a Short Name – this name appears as the text next to the button on the phone.
  • Change Share Call Appearance to shared.
  • For extended function, use this format:  fnc=blf+sd+cp;sub=ext#@serverip;nme=Name 
    • For example:  fnc=blf+sd+cp;sub= This e-mail address is being protected from spambots. You need JavaScript enabled to view it ;nme=Fred

Use the same syntax as extended function to complete the fields in SPA932 tab.  (Sorry, I don't have one, yet.)  Here's what the finished product looks like (sorry, iPhone picutre).

ADDITIONAL INFORMATION FROM A READER:

hey, I noticed one thing on your posting regarding call pickup and the SPA9x2 with BLF.

If you use the *8 syntax, and set all phones into the same pickup group(s), it will work. HOWEVER, you are running the risk of picking up a different incoming call than you thought you were (it is indeterminate which call gets picked up).

A better way is to set the call pickup to *8# on the SPA9x2, and it will then substitute the extension that your BLF button is subscribed to (ie: *8202), which implements the underlying "directed pickup" in asterisk.

Then you add these lines into your extensions.conf:

exten => _*8XXX,1,SET(GLOBAL(PICKUPMARK)=${EXTEN:2})

exten => _*8XXX,n,Pickup(${EXTEN:2}@PICKUPMARK)

and you're good to go.
