Forwarding to freevoipdeal calls enter but No sound on either side

Hi, I just bougth a number and forward to my voip account at freevoip, calls forward ok but NO sound at all, what I’m missing here? I try also GSM codec and nothing. Thank you!

Try the g711 ULAW codec but it could be the provider

I would try the SIP info you have on a 3rd party SIP client

You can always use our SIP info as well
