I think what you are saying is that when phone A uses extension 1 will phone b's BLF-Busy Lamp light up? The answer is no. If you register two devices to the same user number, the most recently registered will receive calls and Brekeke ignores the least recently registered. In addition, there is no code in Brekeke to handle this function. I've heard the function may work with the Saxa phone but it's only available in Japan in that language.
The issue seems to be a difficult one, especially since different phones will handle it differently. Brekeke has yet to commit to a particular phone to do this with. I would like to see them provide this feature for the Linksys line. I have discussed this with them but the project has seems to be taking a back seat to all the new things that have been introduced with version 2. When this version settles down I'm hoping they will address this since it is a very important feature for SMB.
