The spa3102 in located in the 192.168.80.0 network, no firewall, no nat, nothing. I do have firewall in the 192.168.0.0, which is the external network....
Spa3102 simple does not register. I will try to put it again to work and will debug all, from spa3102 and asterisk, and post the results.
The problem with one way voice is with voipcheap trunk - for this one i will disable firewall and see what happens.
Sipgate i did not give i try, because i don't want to add noise to what is not working.
Regarding the files, they are from the 8.10 release, and i sent to see how to make all this work with asterisk realtime in 10.04.
