I am new to VOIP, Linux and Asterisk. Through a lot of reading (this list, voip-info.org, documentation, etc.), I successfully installed FC3 and * on a new Dell SC420 with two X100P connecting to two PSTN lines at my office. I've also installed AMP to help me configure IVRs, call groups, extensions, etc.
I use a Handytone-286 ATA and x-lite clients on the internal network and all works fine. I would like to connect to * as an extension from home, from client sites, from hotels, etc. Most of these places will be behind some type of NAT and/or firewall. At my home, for example, I have a consumer grade firewall/NAT. I cannot get the Handytone-286 to work properly from there. I connect to the * server and register, I can call out and incoming calls ring in, but there is no audio sent nor received regardless of whether dialing out or calling in. I suspect this has to do with RTP and how my home firewall/NAT handles RTP. Is my thinking correct here? What's frustrating is that I can't get it to work even if I put the Handytone-286 in a DMZ. Maybe the firewall/NAT is still processing and malforming the RTP packets? Even if I do get the ATA working fine behind my home NAT, I would have to do some reconfiguration most likely anywhere else I try plugging it in, right? And, if I wanted to add another ATA at home connected to the same remote * server, it's most like not going to work without custom RTP port forwards, etc., right?
