We are trying to deploy the push2phone application and when the web admin (a developer)tries to push a message to the phone, he gets a CiscoIPPhoneError with a value of 4. Checked the enterprise paramaters and found that the URL Authentication value is set for http://x.x.x.x:8080/ccmcip/authenticate.jsp. I have associated with his phone for him to push the message. Still it does not work. Need to know what I am doing wrong here. Thanks in advance.
