Doesn't seem to be that easy for me. I have already created a Device - Phone entry selecting H.323 Client as the Phone Type on CallManager. A DN has been assigned in the correct partition/CSS etc. and the device associated with the required user account in Global Directory (with account enabled for CTI control).
I'm not clear how you set up NetMeeting. I've set Audio up to be CCITT u-Law8.999Khz (in 'Tools - Options - Audio - Advanced') , 8-bit Mono.
Under 'Tools - Options - General - Advanced Calling' I have selected to use a gatekeeper, where I have entered the IP details of the CallManager.
The device in CCM does not register. Is there a more detailed guide anyone can point me at that cover the complete configuration of CCM and the Netmeeting software on the client PC so that I can use NetMeeting to make and receive calls to CCM extensions, i.e. in the same way Cisco Softphone works? Cisco softphone v1.3(3) is working fine by the way.
