IAX trunk to a VoIP Provider

I need to forward calls to a provider(I don’t need the provider calling me). I am not using VPN so I don’t want to open ports from the outside. I will initiate IAX connection to the provider and my firewall will just allow incoming connections that it initiated. I will then NAT(outbound) the IAX port 4569 to a consistent port(the same translated port in every NAT).

Would this be possible with asterisk?


The setup sounds doable. So you should not have much problems when making the setup. Just be careful to set the NAT settings for IAX. I don’t use IAX much, so I can’t give you any sensible advice on that.
