Busy Lamps on Linksys SPA942

#1
Hello,

I have 5 extensions, all on Linksys SPA942 phones. I've upgraded them all with the newest firmware v.6.1.3.(a), which includes support for Busy Lamps.

I understand Voipfone supports Busy Lamps on Snom phones, but is it supported on the SPA942s as well? And if it is, are there any setup tips or instructions? I've tried to follow some generic guides I found on the net (including Linksys' own firmware release notes guide), but no luck, the phone is just not subscribing to the extension I want to monitor.

If there are any tips or ideas, I'd be grateful!

As far as we know, BL only works on snoms.

Unfortunately we can't give you advice on getting these to work with the busy lamp feature. We have found this feature not to work on Linksys phones when testing.

However, let us know how you get on should you get this feature working on your device.

Well i'm not expecting to get this to work, in fact I know I won't because i can only make configuration changes to the phone and not server side as errr you own the server lol. :lol:

There are only two changes to make on a Linksys / Cisco phone in order to use Busy Lamps Feature, the first is to add the following script into the Extended Function Field located in the Phone tab:

fnc=blf+sd+cp;sub=201@$PROXY;ext=201@$PROXY;nme=John Smith

I won't elaborate further on the above script, it will just complicate things, however once it is entered into the Extended Function field you then change the Server Type to Asterisk and finally the SPA932 Call Pickup Code to **#

The # in the above is replaced automatically by the phone with the extension number, so when a remote extension rings and you want to pick it up from your phone after being alerted by the Busy Lamp Feature you press the button and it dials **201 and you take the call.

Save it and that's the phone correctly configured.

All other info instructs you on the correct changes to make to Asterisk in order to complete setup, I assume Voipfone have configured their equipment to work with Snom phones and the two manufacturers require different settings server side? Make the changes so the Linksys / Cisco work would no doubt break the feature on the Snom's? and vice versa and as such seeing Voipfone officially support Snom handsets it makes sense they provide the feature on the equipment they supply and support. (I could be wrong on this bit lol)

As Busy Lamps appears to be a no go then maybe Shared Line Appearance is the way to go with these phones.
