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, 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;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.
