FreePBX 13.0.192.16
Asterisk 13.7.2We have a treatment that calls back callers using callback after a specified period of time.
exten => ****,n,System(/var/lib/asterisk/bin/callback ${CALL} ${DESTINATION} ${SLEEP} &)
The callback drops them off at an FreePBX IVR to confirm that they are there ("press 1 to continue"). After pressing one, the caller is transferred via misc destination to a queue we have on another non-asterisk PBX. If they do not press one, the call is terminated. This has worked very well until very recently.
We noticed on our FreePBX dashboard monitor, the network bandwidth chart (hourly), normally filled with green bars, goes blank. The chart is there, but there are no bars representing bandwidth consumption. Like there is no network traffic. There are still active calls according to the Asterisk logs.
During this time (dashboard hourly chart shows no network bandwidth) agents that are part of the other PBX queue are reporting that calls they are on with callers, that have come through using the above treatment lose audio, drop, or sound robotic. The bandwidth dashboard begins to show data again, then the reported issues subside.
Any ideas on what may be causing this, or where to begin looking? The CPU and Memory and disk all look normal, just the network chart. Could I be maxing out my available bandwidth? I uploaded some pictures to outline what I am seeing.
Thanks in advance!
