as a start: run a debug to see if any RTP packets leave your router and if so, what is their source IP address and so on.

the command is: debug ip rtp packets

might be your RTP packets are NATed or routed incorrectly.

This problem is usually a routing issue. Make sure you have a route back to their voice subnet
