Calls terminated shortly after connecting to an agent.

Hello,

starting today we've been getting random hangups on our calls. The call will connect and an answering machine or person will answer, then anywhere from 7 seconds to 20 seconds later the call will disconnect. So someone will literally be speaking and saying "thank you for calling ..." -pew. You hear the "pew" sound and the agent screen shows the call is hungup.

The campaign dial method is set to Ratio with a level of 1.

I've already investigated the issue with our carrier and they see the calls being disconnected on our end. But when you look at the call history it shows the "HANGUP REASON" as "Caller". It does not happen on every call but it is happening on the majority of calls.

Any ideas?

Can you show me the asterisk log when it happens

Like Chris said yep...the Asterisk logs should reveal what's happening there. That should describe what is happening to the calls.

• cat /var/log/asterisk/messages.x (the date in question)
• rasterisk / asterisk -r

Sounds a bit like the drop call process is kicking in though. That's just a hunch though.

sorry, got bogged down and wasn't able to follow up.

I think it was an issue with my VoIP provider's server. I switched to a different server and the problem went away.
