The way BLF works with sipX is that the RLS engine (the engine that
provides BLF information to the phones in either Broadsoft style or
RFC-4662 style format to the phones) can only propagate accurate
information if it receives accurate presence information from the phones
(if someone could point out the RFC for this latter part I'd be
grateful). The problem that prohibits this from happening is that in
most cases the manufacturers of phones are either targeting the Asterisk
crowd or are developing for a closed proprietary platform. These
platforms generally deal with presence and BLF by examining internal
components of the PBX software to see what the call states are for each
monitored line, not by receiving presence information from the phones.
Because these PBX's don't rely on phone presence information this
results in phone manufacturers like Grandstream (among others) skimping
out on the development costs associated with developing full support for
presence notifications and subscriptions which in turn make the BLF
buttons "not work"
Your best bet is to see if a Polycom phone can subscribe to the BLF of a
Linksys phone (or whatever you have). If you don't see any presence
information it's likely that you've run into the above scenario. At that
point you either need to exchange the phones for something that is known
to work or if you want to keep the phones move to an Asterisk or
FreeSWITCH based platform (or in your case, a Cisco platform).

From what I'm gathering here... sipXecs doesn't support BLF on the
Cisco/Linksys line of ATA phones? Please forgive my ignorance..
but when you refer to "plugin" is that for the sipX generated
configurations? ...or is that regarding support within the presence
server? I noticed that Mr. Sen Heng developed a module for
autoconfiguration.. but what we've been unable to determine is
whether presence would be supported when manually configuring the
phones...
Thanks in advance...

Noone has stepped up to maintain such a plugin for this model,
which is why you don't find it in the sipxconfig menu as a
supported device (no matter how similar to other Cisco/Linksys
products it might be).
I have only seen a few messages regarding this model. Perhaps it
would be a good idea to check what "is" already supported before
buying a device...

Has anyone successfully implemented BLF with this phone? It
is hard to imagine that this doesn't work in consideration of
the sheer number of these phones that have been or are being
deployed....
We've recently purchased 50 for use with sipXecs....
Thanks,
