I am having problems authenticating when connecting to IP Communicator. I am getting CiscoIPPhoneError Number="4". The hardware phone work just fine. Any remcommendations?
Error 4 is an Authentication Error. Basically, you cannot push content to the IP Phone unless you are authorized to access that phone. This works as designed since we don't want someone just being able to push unsolicited content to any IP phone. Authentication is configured through User Preferences/Associated Devices. If you need some kind of broadcast push mechanism, then you may want to create a PhoneSvcsAdmin user account and associate all phone devices to that account.
