[Serusers] rtpproxy for private networks without NAT and way outside

Hi. Assume I have phones in private network 10.0.0.0/24. There is no NAT server in this network, no default gateway, no way to outside world (except SER). The only server phones "know" about is SER. SER has 2 NIC's one in 10.0.0.0/24 network ip 10.0.0.17 and other in "real" word 201.0.X.X/24. There are some phones (or may be SIP servers) in "real" world. I want to force rtpproxy for outside world and do not for private networks. I made some test and it fails. If I contact from private network to outside world the Via message contains private SER ip 10.0.0.17 and phone which I need to contact does not know how to contact SER. Also contact in SDP message contains private ser IP 10.0.0.17 because I have forced rtpproxy. As I understand, it it necessary to modify SDP and SIP messages (contact and Via) in a config script while processing requestst after forcing rtpproxy. Is it possible? May be I missed something, but I have not founded such functions. Regards, Greg. __________________________________ Do you Yahoo!? Free Pop-Up Blocker - Get it now http://companion.yahoo.com/
