[asterisk-users] Polycoms and BLF

[Danny Nicholas]

According to what I've read, you have to have a fully functional MS IM
server running with phones registered to make Polycom work correctly.  I
threw together a PERL script that uses "core show hints" and "core show
channels" together to give an "almost live" (.5 second or so delayed) line
status.

The protocol that the Polycom's use to NOTIFY buddy state is based on
a Microsoft implementation. As far as I can tell, that implementation
has no "Early" state, and cannot therefore report Ringing.

Polycom also support RLMI for BLF type behaviour, which is a full
implementation, but this is not Asterisk compatible. There is a
partial patch to add this in the bugtracker, but I have not tried it.

If anyone knows otherwise, I would be interested to know it.

Regards,
Steve
