Thank you very much qwerty1461 for the sharing. We appreciate it very much.

Thanks for the kind sharing. It is encouraging.

"Works" mean many different things. There are 3G firewalls, SIP Server, TURN Server, STUN Server, etc. Also, there are configuration issues with Linphone and CsipSimple. CsipSimple normally is as good...

Please be specific about what cannot work. SoftPhones using 3G cannot work reliably, without ICE, TURN, STUN, or SIP Server Relay. Our experiences show that CsipSimple is in fact better...
