[asterisk-users] asterisk 13 mixmonitor - random missing syllables
12 calls isn't under any type of load. Someone with better understanding of Asterisk internals may chime in here. Could it be vmware timing? Is timing critical when using mixmonitor? I've seen > 100 concurrent calls being recorded wtihout issue.
