Anyone using 1.8 in production either ST or MT yet?
yes.. lots of installations. MTE parking will not work without patching, its likely digium doesnt care if this works or not. 1.8.4 will crash if you use any pickup. 1.8.3 broke voicemail. In 1.8.5 they fixed a lot of deadlocks, 2 crashes, and removed deadlock avoidance code as it also was causing problems. 1.8.x introduces a new sip message called UPDATE. Versions of siproxd prior to 0.80 will crash when they receive this message (happens after attended transfer).

You need to be extremely careful if you're using 1.8.5 with timerfd timing. This WILL segfault and die a horrid death in certain scenarios (call parking, for instance) due to this patch being pulled:
This is all a very complex ugly mess, but people that don't use DAHDI should probably not be using Asterisk 1.8 at all at this point.
i have had no problems with STE, but I also use the dahdi dummy drivers.
