[asterisk-users] SLA & Polycom

[Andrew Joakimsen]

Has anyone successfully gotten the features of sla.conf to work with
Polycom phones?

I would like to get 501's to show 3 shared lines on each of the keys.
Particularly I am looking for a sample configuration for the phone,
the Asterisk configuration seems simple enough.

I've searched and searched and searched and have not found anything,
general info about SLA yes, but nothing specific to the Polycoms.
