Function fix_contact() is available within mediaproxy.so with same
meaning as its nathelper.so counterpart.

You have to rewrite the REGISTER message before saving the
locations!
if (nat_uac_test("2")) {
force_rport();
fix_nated_contact(); # from nathelper module
append_hf("P-Behind-NAT: Yes\r\n");
setflag(5); #natflag
.....
.....
save(location); # user with natflag set will be
# pinged to keep NAT binding alive

Hello List,
In my fierce battle to overcome the NAT problem I have now running
SER and
Mediaproxy without any problem. Whenever any Nated EP
like to call to
PSTN
or a non nated EP the call goes ok. Whenever I try to
call from a non
nated
EP to a NATed EP the call does not go through.
It seems like that the destination address is not known by mediaproxy
so it
can't forward the call to the correct EP.
My question is whether this problem might be caused by my ser.cfg or
that
this is typical SIP behaviour.
In other words is it possible to call to any EP that is behind
Symmetric
NAT.
