My Zoiper on Iphone couldn't send my voice out. But my colleague's are fine, they call each other and both way sound works fine. Only when I call anybody else, the other side can not hear my voice, while I hear the other side well. The statistics shows no incoming data rate at all on other side Iphone.

As the tutorial suggests, I checked the 'Privacy' settings and try to disable and enable 'STUN', nothing helps.

The problem is fixed by configuring NAT traversing on SIP proxy server (Opensips), together with RTP proxy support on the server too. The reason why I could not hear the other part is still unsure before. Since other people use their Iphones seems don't have this problem. anyway!
