Quickly looked at the file and I see several calls there. All of them
are exposing the issue? Or can you give the call-id of the call that
didn't work fine? I don't want to lose time looking at all the calls,
knowing one that is wrong is enough...
Cheers,
Daniel

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.

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).
