My mistake then. In any case you must complete 2 things. You must first set the flag...or else that part of the code does not get executed.
For example: if (search("User-Agent: Cisco ATA.*")) { setflag(1); # remember this is ATA force_rport(); fix_nated_contact(); };
and your on_reply must look something like this:
onreply_route[1] { if ((status=~"[12][0-9][0-9]")) fix_nated_contact(); force_rtp_proxy(); }
It should work after that.

hmmm. i replaced the INVITE in my original config with the one you supplied and SER started fine:

clients register and get a "200 o.k." response. i just realized that i left out the send and receive message that i get when i try to call a client on the same lan segment - my.public.ip is the ip address of the my.public.box on which ser is running:

the rtpmap messages are new, so i guess that's progress. that said, should i ditch the released version and wade through the config errors that i get when i compile the CVS head? is there anything glaringly obviously wrong with my current setup?
thanks,

Eric,
I don't think the release version has support for RTPProxy. Change your config to this and I bet it won't start.

i've been getting my sea legs with SER and am having trouble getting rtpproxy to nathelper to work correctly with my setup. since everything works fine if i test the scenario with a freeworld dialup account, i'm assuming that my problems are solely due to the vastness of my ignorance on how to configure SER correctly.
i have three x-lite clients [ one is running on windows 2000 not sure of the build number, but it's the latest download from the website; the other two clients are both build 1101 on mac 10.2.3. SER running on a rh9 box on a public IP with rtpproxy. i installed ser-0.8.12-0.i386.rpm which i downloaded from the ftp server. the x-lite clients are sitting behind a linksys befw11s4 nat router.
i can run SER without nathelper/rtpproxy and make and receive calls to clients outside the my network. however, things fall apart quickly when i try to run more than one client behind the nat [ lost audio, timeouts etc] which i presume is what nathelper is supposed to deal with. if try to run to use nathelper, i can't make a call from a one client to another client behind the lan. the calls won't go through - they simply timeout.
i downloaded and compiled rtpproxy which i obtained from the portaone website and simply started it from the command line. i can't figure out how to get any debugging messages from rtpproxy, but i can see that the process exists and /var/run/rtpproxy.sock is created.
i altered ser.cfg using the template i found in the ser-0.8.12_src tarball [ /modules/nathelper/nathelper.cfg ]. see my config below [1]. i understand that things have changed quite a bit in the CVS head, but i tried to compile and install the latest CVS version, but i ran into a host of config errors using the nathelper.cfg supplied, so i decided to backtrack, gather my wits, and stick with the released version.
the x-lite clients appear to register appropriately with the server [2 - public ip addresses have been changed to protect the innocent]. to my untrained eye, these messages look the same as what i see when i test things using freeworld dialup accounts and i can make a call to another client on the same lan segment - i.e. the internal IP addresses are being sent. the location database also shows that the internal IP addresses are being used [3], but i don't know if this is what i want or not. oh. i'm also using my.public.box - a FQDN - as in the x-lite fields where it asks for "Domain/Realm", "SIP Proxy" and "Out Bound Proxy".
so anyone care to grab me by the lapels and point out what i'm obviously doing wrong :-)
