Hi All, We're experiencing some difficulty with low ASR (around 50%) under high offered load on an Asterisk 1.6.1.9 system with libss7-1.0 and a Digium TE410P, 120 channels. Application is standard missed-call-notification, so obviously many calls being abandoned after a short time, but still a test system carrying the same traffic with proprietary software on Dialogic hardware has an ASR in the high 90s. Only hint I have at this time is a high number of circuit resets apparently being done by Asterisk; I wonder whether these might conflict with offered calls on the same circuits. CPU load is negligible, everything still running from RAM, so I don't see it as hardware constraints. Other suggestions perhaps, anyone? Cheers, Charl
