Occasionaly users report no audio when making calls on their CIPC phones over a VPN Connection. The only difference I see between a working phone and non-working, is the non-working CIPC has an IPv6 address assigned. The same CIPC phone works one day and not the next.
CUCM 8.6
CIPC 7
Where would I start looking for the problem?

Hi,
Please check if the correct Network Adapter is selected by navigating to CIPC->Network->Device Name
Hope it helps.

This had to go back burner as we moved through a large project but now it's returned.
Some more information - The Network Adapter uses SEP00000000XXXX where XXXX = the extension number. This is set in Call Manager and the device. The users connect to the home network through AnyConnect v2.5. This device does register with call mananger however its IP shows as 192.168.1.4 which is the IP on the devices lan.
