We’re using FreePBX 2.10. Often, when callers call in and hear our IVR, the audio cuts out (dead air) for 1-2 second intervals; also, dialed digits for the IVR system are missed and need to be re-entered. We have the same issue when users are checking voicemail - essentially any recording played from FreePBX. While on the phone, we have no quality issues at all - any idea of where to look on this one?
It’s definitely not the DTMF signaling - outbound calls work 100%. I know the IVR menu navigation is related to the audio cutting out…it’s like the FreePBX system gets lagged and can’t respond fast enough (although resources are just fine).
I believe we have a related issue: Calling is fine, but when an incoming call is entering the privacy managers message, the message gets cut off randomly, leaving the caller in the blank. This also happens if a caller enters the voicemail and freepbx plays an audio message. I can’t see any strange things in the logs. I’m wondering if it could it be the Virtual Machine.
