Although not easy on a production system, your best bet is to catch the behavior in the act. Usually this means that you have to rely upon humans to report the symptoms to you in a timely and accurate manner. One way you can help track these down is to use something like pcapsipdump and do a ring buffer that covers at least several days. Then, when you hear about a symptom you can go back and look at the corresponding pcap file which will have both signaling and audio. From there you can hopefully trace the root of the problem. -MC http://wiki.freeswitch.org/wiki/Packet_Capture#pcapsipdump On Fri, Oct 28, 2011 at 9:19 AM, Jason Moran <jmoran@secureachsystems.com>wrote:
I have some questions about the types of statuses we are getting (Yes, I’m already familiar with http://wiki.freeswitch.org/wiki/Hangup_causes )* ***
** **
We just deployed FS to production a couple of days ago and here is a sample of our Hangup Causes:****
CALL_REJECTED 1****
NO_ANSWER 738****
NO_USER_RESPONSE 175****
NORMAL_CLEARING 1667 (Expected that this is only Early Hangups)****
NORMAL_TEMPORARY_FAILURE 4****
NORMAL_TEMPORARY_FAILURE (Rang) 37 (Rang means this status happened more than 5 seconds after the session was started)****
Complete 224 (Complete is our own status instead of NORMAL_CLEARING, meaning WE hung up because we finished the entire message). ****
ORIGINATOR_CANCEL (Rang) 3****
RECOVERY_ON_TIMER_EXPIRE (Rang) 9 ****
UNALLOCATED_NUMBER 2****
USER_BUSY 35****
** **
My questions:****
**1. **NORMAL_TEMPORARY_FAILURE happens a lot, and often returns 30 or more seconds after starting. Could this be a “silent call” (etc)? We have gotten 3-4 complaints of silent calls and I’m hoping to find the cause.*** *
**2. **Is there anything here (or ideas elsewhere?) to explain why a call will be silent once in a while?****
**3. **Is this spread of causes normal or does it seem strange****
**4. **We’ve had a few people note that the message on their voicemail is over before they can hear it - even though we play the message twice (to make short messages longer). Does anybody know of a solution for this?****

Thanks! -Jason****
