Hi guys,

We have 2 seperate sites with 2820 routers, and a 2820 at our office, either of the sites can use their VPN to connect to the office with their IP phones and can talk to people in the office without issue, however if the 2 sites try phoning each other over the VPN's, they will connect but no voice transmission is heard.

I have done some research and it points to Payload between the 2 VPN's, the router must route the payload down the VPN tunnel to the other side, any idea what i need to check is set for this to work correctly?
