Hi all, I've a problem beetween X-lite softphone and Cisco Sip Gateways. Both SER and Cisco Gateways are configured with public ip addresse, while the x-lite is behind a nat router. It seems that the x-lite doesn't take into account the ser ip address in SDP connection information field but it sends rtp to the ip of the cisco gateway.

Can someone help me ? How can I try to solve the problem?

Thanks Carlo
