[SR-Users] Kamailio and rtpengine - client behind NAT

Hi
I'm still struggling with this problem. My setup is:
mobile ---- sipproviderA ---- kamailio1 ----- kamailio2 ----- SIP
user 20111101
The SIP user calls the mobile and every thing works fine until the mobile
hangup and the sipproviderA sends a BYE to kamailio1. That bye message has
to "Route" headers:
Route: <sip:188.166.3.25;lr;nat=yes>.
Route: <sip:188.226.200.111;lr>. <---- IP of kamailio1
Kamilio1 just forwards that message to kamailio2 and sends it back to
kamailio1. BYE is then never send to the SIP user. I don't know why
sipproviderA would send such a message. Maybe it si because I'm sending
something strange to sipproviderA when the call is established or maybe
sipproviderA is just sending a strange BYE message. Any ideas?
(I have testet with another SIP provider where everything is working fine)
I can solve the problem by doing very ugle hack in kamailio1 and I think
this can be done better?
-----
dns_query("sip.sipproviderA.com", "sipproviderA");
if (is_method("BYE") && $si==$dns(sipproviderA =>addr) && search("Route:
<sip:188.226.200.111")) {
xlog("L_INFO", "MS: RELAY remove double route from $rm
si=$dns(sipproviderA =>addr) from ($fu:$sp) to $ru\n");
remove_hf_value("Route[-1]");
}
if (!t_relay()) {
sl_reply_error();
}
-----
I have included an ngrep from kamailio1 below.
Cheers,
Martin
