Audio is not clear in the calls (Choppy / Garbled)

[siscom]

Good Afternoon Colleagues
I hope you are fine . One of our customers has 3CX 4 concurrent calls 18.0 Update 9 (Built 20) . There is SIP trunk with a local SIP trunk provider . Everything was working as expected till today.

There is an issue that arise that audio being not clear at all (Choppy / Garbled) for both internal and external calls.

Attached is an internal call between two local extensions.

So kindly advice what should be the issue ?

Best Regards

So if all is working but except today you need to ask:

- Has anything changed on the PBX?
- Has anything changed on the network?
- Has anything changed that could cause me problems?

If the answer is no to all of those, go back to your trunk provider.

CPU usage on the 3CX server? Restart 3CX services? Phones/devices are all on LAN for the testing? Internal calls wouldn't be the trunk.

There are many facts that you need to be aware here.
From which side the audio was choppy? Did you run captures to check?
Furthermore why not upgrading to V20 and use our Connection Quality:
