Hi all.
Using SJPhone, I have found a serious drawback. It is not capable of using my SIP freephonie.net account through a nat'ed router. Too bad.
Last week, my SIP hard phone failed to get a carrier. I used my soft phone to make calls. X-Lite works like a charm using my freebox in router mode. SJPhone not.
I am not sure it is only a SJPhone problem, because it works with voxalot, pulver.com. So ?
In fact, the only thing I am sure, it is that you always must test any VoIP equipment (phone, router, SBC, firewall, ...) deeply before adopting it.
The VoIP protocols are so complex that between two architecture, there is probably something that is not supported :-)
