Steffen, thank you for quick response!
I'm checking with Broadsoft as well, but would like to hear from Polycom as well (as I can't find the answer in any of the documentation).
Did you mean R20 where this feature is introduced?
If you could put me in touch with Polycom SE, it would be great.
I'm just trying to clarify here what we should expect from the feature (as we can login/logout, get DND and CFWD sync... and not much else).
Partner confuration guide seems to describe it's either Call Center (ACD) or Flexible seating;
i.e. parameter voIpProt.SIP.acd.signalingMethod should be 1 for ACD and 0 for Flexible seating.
