Hi Kouao
IAX2 should work out of the box, did you change some settings manually? I suggest checking
1. IAX2 module (Settings=>Technology Settings==> IAX2 Settings)
2. Firewall ( ADMIN==>Security)
Make also sure that traffic from port 4569 is seen on both sides, just to make sure that NAT routers or external Firewalls are not blocking the traffic
