There is a module in development which implements BLA/BLF in OpenSER and supposedly works
with Polycom phones. Given the lack of a standard I suspect you'd have to adjust your
configuration to accept different event types from different phones to make them work with
this module. We are just beginning to work with this module. I'll post more
information about our experience as we learn more.

Subject: [OpenSER-Users] Presence BLF in OpenSer?
Hi, many phones as Thomson S2030 or Grandstream 3000 allow presence
BLF.
Unfortunatelly I think BLF (Busy Lamp Field) just works with Asterisk
and it's
not a RFC or a draft.
Thomson S2030 allow subscribing to a extension state and it generates

Is there any possibility to use this BLF feature with OpenSer in any
way?
