The headache we went through to get this working outweighed the additional costs of Cisco's 7937G (which is a Polycom IP7000 running SCCP), so we're now exclusively deploying 7937G's instead of these. This configuration reference just helped me register the same phone, and I couldn't find this information (easily) anywhere on Polycom's site. Kudos and thank you! ... View more

Has this worked for you in the past? The original link that you posted 5 years ago is dead, but the bug still exists. However, it doesn't mention CDC being the issue. Do you recall this? ... View more
