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;
