Hmm, I have no heard before about BLF functions of Linksys SPA94x or
92x. Is there any documentation how can I setup this?
I know also about SLA, when using this devices with SPA9000. But in this
case it need to enable SIP-B on phones for work LEDS as BLF for SLA lines.
If so, this seems like a hack but it makes a trick.

PS. This will be useful option for Linksys users.
