[asterisk-users] BLF Compatible Phones

I'm using Aastra 57i + 560M sidecars for receptionists... the only downside
is that they support a max of 50 BLF subscriptions... you can setup up to 180
blf keys with 3 560Ms but it will still only subscribe to a max of 50... from
what I understand it's a firmware limitation.

For 4-6 phones you could probably get away with doing it directly on the 57i
with no 560M's (or 536M's) too many more phones and you'd need the
sidecars just for the extra buttons I think.

Subject: [asterisk-users] BLF Compatible Phones


I am new to asterisk and am looking to setup a small office with 4-6 IP
phones and 4 analog lines from the local telco (primary line with HUNT
to the other lines). I am considering purchase of a Digium AEX800.

One of the features that will be important (particularly for the
receptionist desk is to show status of the other lines in use). I don't
want the receptionist to pick up a line if it being used.

Is there a list of phones that are BLF (Busy Lamp Field) compatible? I'm
assuming (after reading tons of misc articles) that this is what I need
in order for the receptionist not to pick up lines in use. If this is
not the case please set me straight.

I am considering the cisco 7960's, linksys SPA942, and possibly some
polycom phones. I was leaning toward the 7960 but I've read that it is
not BLF compatible. Are there any workarounds for this? I am new to the
game and would be grateful for any recommendations on which phones would
be the easiest to setup, etc. I currently have a working asterisk
install at home with a single cisco 7960 registered which isn't hooked
up to any trunks as of yet.

Thanks,

Dayton Gray
