Download PCAP Files

Additionally, Voice Gateway provides PCAP files, which can be downloaded in the detailed information overview.

Call Tracing

This feature is in beta. The data displayed on the Tracing tab does not have persistent storage and may be lost at any time.

For inbound calls, you can analyze the captured media stream (log) to diagnose and troubleshoot voice quality issues by clicking the Tracing tab and viewing the report. This feature provides valuable insights into the duration of different actions during the call, such as speech recognition and connections. By reviewing the report, you can identify any delays or issues that occurred during these actions, helping you pinpoint potential areas of improvement in terms of performance and efficiency.

To view details of the log step, click the duration indicator of this log.

Call Recordings

Record your calls while setting up your voice agents for debugging purposes. This approach lets you troubleshoot your calls, identify where latencies are coming from, and listen to your voice agent’s outputs to ensure they are working seamlessly.

To enable call recording, use the Account or Application settings.

When call recording is enabled, you can use the embedded media player to listen to recordings of calls. Note that the recording will consist of only the caller track and the agent track. The dub track for Atmosphere Sounds will not be included in the recording.

With the included media player controls, scan the audio and download the recording locally.

When you click highlighted STT and DTMF events, a new window will open, presenting the speech-to-text result along with specific parameters:

• Vendor — the STT provider used. For example, deepgram.
• Confidence — the confidence score associated with the transcription result. For example, 0.9760742.
• Language Code — the language code for the transcript. For example, en-US (American English).
• Transcript — the actual text generated from the speech. For example, Today is Wednesday evening, ten-thirty PM.
• Latency — the time delay in processing the speech and providing the transcription result. Voice Gateway is waiting for a response from the transcript server.

You can delete a call recording by clicking . Note that this action will delete your file both from Voice Gateway and remote storage, for example, Amazon S3.
