Need Help

Hello friends. I need your help. I'm noob.
I installed ejabberd, launched, threw ports and everything kind of worked. I use the bundle Ejabberd + Astrachat. I read that ejabberd supports jingle. When I call from 3g 4g, I get a connection reset and a "MISS CALLED" message. If at least one of the Astrachat customers is on the same network, where the server then the calls go without any problems. Help me to understand . Thank you. Sorry for my English.
