I have 2 accounts on the test asterisk server, voipgw.u-strasbg.fr, and I'm trying to call one from the other.
Both of my machines are behind the same firewall/router (I have a DSL connection). I'm not able to even simultaneously call one of the test mp3 numbers like 669, from both of them. They are both set up with the same port numbers, etc.
Is this even possible, what I'm trying to do? If so, do I need any special settings to get it to work?
