Asterisk Sip trunk though a PIX 501 firewall

Question

I'm using an asterisk VOIP server, and I'm able to make called though with my SIP client. The problem I get is one-way voice. I can hear the incoming voice but the caller can not hear me. I have no problems when using the X-Lite3 windows SIP client. I VOIP provider is broadvoice.

Could it be something in the firewall rules that I need to fix?

Both comments helped. I think the nat=yes was the fixing point of it – Squidly May 06 '11 at 01:01

There are several options you need to set correctly to make it work: localnet, nat, externip or externhost, qualify, canreinvite, etc.
