Hi, I'm running Callmanager 5.0(4)
I can autoregister and manually add 7960's as SCCP phones with no problem.
When I try to autoregister or add them as SIP phones I receive a 'Registration Rejected' error.
I can register 3rd party SIP phones with no problems.
I'm not associating any users or digest authentication on the 7960's, I don't think this should be necessary?
The Callmanager has been installed with a default configuration.
Does anyone know what is causing this?
