It has been awhile, but I think I was running 1.6.1 last time I tried. I just had strange things like my trunks going unregistered at random times, qualify=yes settings causing call failures because of QOS or something I don't remember. Overall it was just a little strange and I started getting burned out messing with it. After I got the GS from VOIPo and found it to work so well, I just went back to Asterisk 1.4 to play with using some other PAYG services.
