Yes there are NATs everywhere. The Asterisk server is behind a NAT firewall. The softphones are on laptops that wonder around to various clients who are on their own NATed networks. The Grandstream is at my house which is behind a NAT. It will be going to a different location once this resolved.<BR>

Bob, this sounds like a NAT issue. When you're outside the office are the softphones behind a NAT firewall? Is the Asterisk Server behind a NAT firewall?<BR>

Hi guys,<BR>
<BR>
I've been testing softphones in Windows and SuSE. From outside the office, I can make a call to a different extension and to an outside number but neither the caller nor the callee can hear anything. I thought I was being stupid until I bought a Grandstream GXP 2020 which wouldn't speak to me either from outside the office. It does work inside the office. I tested the softphone inside the office and it works too. Ok so it's the firewall. I have port 5060 UDP and 10001-20000 UDP open and pointed to the Asterisk box. What am I missing? I'm getting so close to being able to go live with this thing.<BR>
<BR>
Thanks<BR>
