i have been searching the web for solutions but couldnt find any hints on how to solve my problem. I use Asterisk verion 1.4.18. Also i registered for an account at sipgate.com. When i try to dial a local number a friendly computervoice tells me that i dont have enough money. So outbound calls seem to work. When i try to call my voip-number, i can see the incoming call but i cant hear a person speaking (on both sites). What could be the problem for that? I mean, if nothing would work i also couldnt hear the computervoice from sipgate.com ?
The asterisk server is behind a firewall. All ports for rtp.conf (already checked rtp.conf) are accessible.
thanks for help and best regards
