I loose voice after install DynDNS

Hello All,

I installed my asteriks box work fine and I don’t have a public IP address for outside of my network, so I decide to use the DynDNS, and everything sound good, I can make a call, from outsite of my network, but I don’t have anymore the voice (sound) when the phone ring and pick up, there is no voice, I can’t hear and they can’t hear me.

So any help, I don’t know why that happen, where I need to check?
