We have two offices (China and US) connected by site-to-site VPN using 2 Linksys RV082's. We also have a VoIP system with 2 VoIP phones in the China office. We have been having trouble with the phone connections, and our VoIP provider is asking me to have the China phones route over the VPN before going out to the internet.
US LAN = 192.168.188.x
CHINA LAN = 192.168.166.x
I can manually set the IP on the phones in China. How would I force the phones there to go out to the internet across the VPN first? If they have a 192.168.166.x IP, they will go to the China router and then out to the Internet. Is it possible to force them to go to the US router instead of the China router?
Any ideas would be greatly appreciated.

The VPN concentrator is on the same subnet? Change the default gateway on the phones. You may have to meddle with MTUs, though.
