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,

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)

<miconda(a)gmail.com <mailto:miconda@gmail.com>>:
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.
