I would first try it with standard NAT. It depends on the exact setup on both sides, but it's common for VoIP providers these days to handle various NAT based configurations in their border controllers or SIP servers - the first troubleshooting step from their side would often be to *disable* any "nat helpers". If that's no good, try restricting each ATA/phone to a different RTP port range and port-forward them.
