Hi Anthony, thanks for your response ...
this is what i have:
esl_filter(&handle, "unique-id", esl_event_get_header(handle.info_event, "caller-unique-id"));
esl_events(&handle, ESL_EVENT_TYPE_PLAIN, "CHANNEL_DATA CHANNEL_EXECUTE_COMPLETE CHANNEL_HANGUP");
what do you suggest i put there ?
is the inbound method less costly ?
I modified testserver.c just a bit...

try removing the filter and event subscriptions
it's costly to consume all of the events especially at 75cps.
