We have two Polycom CX3000 conference phones. They have worked great for us the past 2 years. We initially had some troubles getting them to sign in and I believe it came down to some certificate issues. Last week on our lync 2013 FE server the default certificate expired. This was all configured before my time at the company and whoever configured things initially is no longer with the company. I stumbled through getting the certificate renewed and lync is up and running fine. We have 50+ Polycom vvx410 and 500 models that are working fine.
On the cx3000 that will not sign in. It asks if you have a computer to make signing in simpler and connect the USB. When I connect the usb it never prompts me to login on the Lync client. I have tried connecting the phone to several different PCs to see if connecting through USB ever prompts for login info. Nothing ever happens. When I go to sign in using extension and PIN it tries to login and flashes a few messages very quickly before saying an account matching this phone cannot be found. I have tried several different extensions and PIN combinations that sign in no problem on our VVX phones.
The CX3000 is version: 4.0.7577.4455. It is picking up a good IP. When I test the account with the Test-CSPhoneBootrap -PhoneorExt everything comes back successful.
When looking at the time in the system information it is 2 hours off. I believe I remember that being a problem in the past. Not sure where it is pulling its time from.
Any ideas?
