下面这段是注册代码：

char localip[128];
static int flag = 0;

sprintf(identity,"sip:%s@%s",username,localip);
sprintf(registerer,"sip:%s:%s",ip_url,port);
//初始化

}

//注册失败之后，再次提交授权信息， 也可放在上面
eXosip_add_authentication_info(username, username,password, NULL, NULL);
}
if(je->type == EXOSIP_REGISTRATION_REFRESHED)

}

}
ps：注册其实挺简单的，代码是用eXosip实现的，帮助手册上面都有，只要细细分析就能看明白，网上有pdf版本的，csdn上也有，英文的。
