Hello,
I spent some time getting a seperate Asterisk box configured with SME7 acting as a natted firewall.
Anyhow this configuration works just fine with portforwarding rules and quality is great.
I have gotten requests however from some folks to have Asterisk installed on the same SME box and while I have my own personal reservations I wont go into it here. The basic questions I have are -
1) Is the Asterisk panel /install work with smooth install? I had some issue with log file locations and expected directories missing. I saw these in the bug track and "Me again" posts but didnt seem to see a definitive "yeah it works".
2) Does SME 7 by default have QoS enabled? The search posts as well were not so clear.
