I can ping my router, 10.100.1.1, my CCM 10.100.1.2, but not any phones 10.100.100.x. I can ping the phones from the CCM or the router, but not from a workstation on a different VLAN, or from a VPN client. Is there a firewall built into CCM preventing the pings, and could this be what causing my audio problems?
You may want to look at the audio set up of the softphone. On the softphone, go to Settings>Audio>Network Audio Settings. Then do specify address and put the IP address of the PC/laptop you are using. I had the same audio issue when using the VPN and softphone.
