Hello Per,
Without more data than you've given it is very difficult to comment on your problem with these contribs which aren't working properly. However, there is only one area where SAIL impinges upon the rest of SME Server and that is in the rewrite engine in Apache. SAIL modifies the engine to do direct proxy to local phones. You can turn the proxy code off (i.e. - remove it from Apache) by setting
Dynamic Proxy Enable: to OFF in globals. This should prove whether the problem lies with SAIL or not. If things work OK with the proxy OFF, then you can turn it back on and use the
Proxy Ignore List: feature to force it to ignore your contribs. In this way both SAIL and your contribs should be able to co-exist peacefully. You can read about proxy-ignore here
http://aelintra.com/docs/cgi-bin/view/Main/DocChapter06#Proxy_IgnoreAs far as reporting bugs is concerned, because we are only dealing with one product which is reasonably stable, we don't really mind where you post errors. Feel free to leave them here or on the bug tracker. The SME developers have a strict rule that all their problems are reported on the tracker, but they have a much larger problem space to tackle than we do, so it's important to them that you report SME bugs only through the tracker.
Kind Regards
S
