Hi, I hope someone can help me. I've scoured the forums and support documents but can't seem to determine why my 1760-V Gateway won't register correctly with my CUCM 8.0.2 running on VMWare. From my reading it looks as if they are communicating with each other but just doesn't seem to register properly. Or whether it has in fact and I'm just being stupid. Your help is greatly appreciated Voice-GW#sh version Cisco IOS Software, C1700 Software (C1700-IPVOICE-M), Version 12.3(11)T11, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2006 by Cisco Systems, Inc.
