Dear mates,

I tired Linphone as a SIP client to call another linphone client. Failed.
Topology is that

Linphone LegB--\
                       ---------------Wifi NAT router -->Internat-->[ Kamailio (inet IP) -> FreeSwitch (same host as kamailio)]
Linphone LegA--/

Both Legs could attend a audio conference. Linphone could reach a CSipSimple client . BUT they cannot call each other via extensions.

Linphone clients settings:
Stun Server specified
TCP connection
Linphone logs( wireshark decode)

I asked Freeswitch some days ago and they tell me it is a NAT issue, while kamailio dev say my kamailio works even in an enterprise environment. I have no clue and call for your help then.
