Hello,
I am setting up some of the mentioned sets on our Genband C20 phone system. I have figured out how to assign existing lines in our system to the Polycom phones as MADNs. Is it normal for the Polycom sets to not show an off hook indication when the other existing phones are on a shared line? Also I noticed that the existing sets don't show an off-hook indication from the Polycoms until after the calls have been dialed. The version of the Polycom I am testing with is 5.2.0.8330. Hope this makes sense. Thanks.
