I believe that SLA on the Polycom phones is based on the "Broadsoft
SIP" implementation.

You can read more about it here:

Mark, you will be very dissapointed with the Asterisk SLA "feature."
Caller ID does not work, neither will the redial or call logs on your
phone. In the sense that the line is shared, yes it is. But that's
where the function ends too. I would say the feature is in alpha
testing right now -- it can not be used in a production environment.
You will not find much information about it, I assume because those
that have actually gotten it to work realized its more of a joke than
anything and gave up on trying to use it.
