How to set up nathelper/rtpproxy when both SIP UA's are behind same NAThttp://openser.org/dokuwiki/doku.php/examples:caller-callee-behind-same-nat
or
if use the avp modules, by checking in location tables by using avp_db_query and avp check of recieve parameter, this depends on UA's Client.

Hi,
I am using .nat_uac_test to detect if the UA is from behind a NAT and if so use rtpproxy. However, if both UA are behind the "same" NAT, is there anyway to tell? If both UAs are from the same LAN then I don't need to apply rtpproxy.
What would be a good way to do that?
Any suggestion will be greatly appreciated.
Regards, Pete
