[asterisk-users] Sound through NAT issue

[Paulo Santos]

Hello everyone,

I'm having a hard time configuring my router to forward asterisk traffic 
correctly. I have the following ports being forwarded to asterisk:

5060, 10000-20000

Now, I can register the accounts when outside the network and I can call 
every extension that is inside the network. The problem is that I can't 
ear anything nor can the phones inside the network phone the outside phone.

Is there any port I'm forgetting to forward?

Best regards,
Paulo Santos
