[Asterisk-Users] SIP-firewall problem?

[Paulo H. Mannheimer]

Hi,

I have asterisk working well on my intranet, using SJPhone to make SIP calls. 

Everything works fine except when I try to connect from outside my intranet. 
I've opened the 5060 UDP port on my D-link firewall/router and, although I can 
dial, complete calls and hear the other party, my voice gets lost (the other 
party does not hear me).

I've took a look on the >sip debug output and everything seems fine. Any other 
hint on what am I missing to configure on my firewall?

Best regards,

Paulo Mannheimer
