Hello,
I'm facing issues with far-end NAT traversal this case being, (wifi to 3G) is still not working. I am using Linphone-Android, one on 3G and other behind Wifi router. I am able to call from 3G to Wifi, Wifi to Wifi (using same Wifi router) but for some reason, Wifi to 3G is constantly getting RTO'ed. Please note that even though it is not responding to INVITEs sent by SIP server (on the specific IP:port), it is very well responding to the keep-alive OPTIONS messages from outbound-proxy. Below is the trace of what is happening on my systems - Registration of UAC Behind WiFi ******************************* UAC ------> Proxy ----------------- REGISTER sip:188.227.178.226 SIP/2.0 Via:
