Can you attach a pcap with such situation, which includes the REGISTER,
replies and the call showing the issue?
Cheers,
Daniel

sorry，I have not expressed clearly.
kamailio will recive two REGISTER at a time.In first 200 OK to
REGISTER, Server will tell Linphone the Linphone Nat Ip and Port.
like this:
Via:SIP/2.0/TCP
30.9.2.1:50691;received=42.1.7.1;alias;branch=z9hG4bK.kmhC2L9Rf;rport=33746
and Linphone will know it's outside nat Ip and port, Linphone while
use this Ip and Port in second REGISTER.
like this:
REGSITER
Contact:<sip: 42.1.7.1:33746;transport=tcp>
So kamailio server know Linphone's nated ip and port and save in
DB(contact field).
my question is KA_EDGE receive sip from KA_REGISTER already have right
nat ip and port like
INVITE 123456@42.1.7.1:33746;transport=tcp SIP/2.0
but KA_EDGE do not send this sip msg to 42.1.7.1:33746
<http://42.1.7.1:33746>, it send to another nat ip and port(other
Linphone's ip and port behind same NAT layer)

Indeed, the ports are different, that's why adding received is
important in this situation.
While local ip and local port are in most of the cases also unique
for devices behind a nat router, it is not 100% true, because
there can be many layers of NATs, which can result in seeing same
local ip/port for devices.

source IP is same, But port is different。
like INVITE sip:Linphone_nat_Ip:Linphone_nat_port;tcp;

Adding received information to Path helps to identify
properly the connection to be used. Because both devices are
behind the same NAT, practically they show the same source IP
when they send traffic to server.

KA_EDGE have two IP，external public IP
and internal IP.
I add modparam("path", "use_received", 1) and replace
add_path() to add_path_received() in edge server.
add modparam("registrar", "path_use_received", 1)
in KA_REGISTER server.
DB path info <sip:aD15fXXXXXXXXXXXXeEpfqRY=@10.10.10.11
<http://10.10.10.11>;lr;ob>
-->
<sip:10.10.10.11;lr;received=sip:42.129.1.1:43640%3Btransport%3Dtcp>
This kind of situation very little，It is not easy to reappear.
Can you tell me why this situation happen? and Why this
change can solve the problem?
Thanks for Your Time.

Yes，Use Path in DB. like
<sip:XXxXXXXXXXXXX/ogxZg=@10.10.232.29
<http://10.10.232.29>;lr;ob>
KA_REGISTER wile the path info in DB.
Should not be a problem if you use the use_received
options in
http://kamailio.org/docs/modules/stable/modules/path.html#idp135216
and
http://kamailio.org/docs/modules/stable/modules/registrar.html#registrar.p.…
(and actually add the source as received on the kamailio
edge server).
