Project ID: p\_26f0goz6ays  
Call ID: \*\*SCL\_aZzv5Vp8mGBo

I am trying to understand why certain calls have bad audio quality where our agent doesn’t seem to be able to understand what the user is saying. Not able to download the PCAP file, its always empty, we are using livekit cloud, is there some setting that we need to toggle to get PCAP files?

That call, `SCL_aZzv5Vp8mGBo`, looks like it connected and then ended almost immediately, which probably explains why the backend did not generate a pcap.

See the event log at [Sign in | LiveKit Cloud](https://cloud.livekit.io/projects/p%5C_/telephony/SCL_aZzv5Vp8mGBo/outbound)

The time between started and connected is much longer, which threw me at first.

Thanks for the reply, the call was actually 8:06 mins long, we have the transcript and the audio recording as well, on the livekit dashboard it shows it took 6 mins to connect which is weird. The audio recording has almost 30 seconds of ringing and then the call connects with conversation between the agent and user. In the middle of the call the agent is unable to hear the speaker, so we wanted to take a look at the PCAP file.

Update, this looks like its tied to our SIP provider DidLogic, all calls with DidLogic are missing PCAP files, others are fine.

I see what you are saying, I was focusing on the SIP event log, but the room events show the room existed for the full 8 minutes, like you say.

If I look at the server logs for that time I see a lot of out of order packet reports at our SFU for that call.

There isn’t usually a single root cause for this, it’s usually a result of network issues or mismanagement of media streams.

Since this only affects your DidLogic calls, I assume it’s some connectivity issue… do you have the PCAP files from their side?

I searched internally and on our public forums, and I don’t see any other related issues for DidLogic in the past

Thanks for checking, have asked them for the PCAP files, will get back to you once they do.
