Switching off audio verification in SIP Tester helped to reduce delays in media thread. It should be done by a separate process with lowest priority. We will work on it.
Less than 10% of calls passed through 3CX PBX. Reason is definitely in license limits - 3CX plays this message. It is strange because SIP Tester did not generate more than 4 parallel calls. We will re-test 3CX with higher interval between calls, hope that it will help. Reason of high answer delay (7.7 seconds) is also in license limit.
