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
