We are facing a strange issue with our FreePBX 17.0.28 version application. Every 3-4 days suddently users cant able to hear properly (voice break)and calls wont connect. After restarting the VM server, its works perfectly and again same issue repeats in 3-4 days. No network latency and enough resources are assigned to the VM. What could be the reason? anyone experienced the same issue.
Since restarting the VM temporarily resolves the issue, it seems like something is degrading over time rather than a permanent network issue.
The next time it happens, before restarting, could you check the Asterisk logs (/var/log/asterisk/full) and confirm whether the endpoints are still registered (pjsip show contacts)? Also, which Asterisk version are you running, and does the issue affect both internal and external calls?
That should help narrow down whether it’s related to PJSIP, RTP, or another component.
