You are new to this! A good victim... ( you really need to read a bit, start by downloading Asterisk, The Future of Telephony from a site like
http://cdn.oreilly.com/books/9780596510480.pdf or read the online html versions. Then either print or buy a copy to mark up as you learn)
That is actually the way I set the context statement in my settings. Unless you have specifically created a working [from-voipo] context in the configuration files, I would not use that.
The settings to 'publish' your * box location to the external world will depend on whether your IP is static or dynamic. and your domain name.
For example, I use static IPs and have statements 'like' (meaning these are not real) this in the sip.conf files:
externip=72.85.94.206
localnet=192.168.45.0/255.255.255.0
On my PBXiaF box, I insert them in the sip_custom.conf file since the sip.conf is automatically maintained by FreePBX (in other words, don't change it, it will just get over-written). I have not played with TrixBox since they went a bit over the edge a while ago.
There have been some good recent discussions of proper setups for asterisk over at the
