Call records stream data coming null

Question

Call records stream data coming null

Neema001 51

I have created a subscription to /communications/callRecords.

Assigned CallRecords.Read.All permission to App in App registrations.

I did call through teams in web browser , have got the call id via webhook and was able to retrieve call record through https://graph.microsoft.com/v1.0/communications/callRecords/786cc488-914f-455d-a5c4-dec5d329ef98?$expand=sessions($expand=segments)

But in its output, streams field has all values as null. I am getting only 2 fields everytime, averageRoundTripTime and packetUtilization. Apart from these 2, all other fields are always null

"averageAudioDegradation": null,

"averageJitter": null,

"maxJitter": null,

"averagePacketLossRate": null,

"maxPacketLossRate": null,

"averageRatioOfConcealedSamples": null,

"maxRatioOfConcealedSamples": null,

"averageRoundTripTime": "PT0.303S",

"maxRoundTripTime": null,

"packetUtilization": 5782,

"averageBandwidthEstimate": null,

"wasMediaBypassed": null,

"postForwardErrorCorrectionPacketLossRate": null,

"averageVideoFrameLossPercentage": null,

"averageReceivedFrameRate": null,

"lowFrameRateRatio": null,

"averageVideoPacketLossRate": null,

"averageVideoFrameRate": null,

"lowVideoProcessingCapabilityRatio": null,

"averageAudioNetworkJitter": null,

"maxAudioNetworkJitter": null

Can anyone help ?
Does it matter whether call is made using browser or teams desktop app ?

Hi @Neema001

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is related to Teams development, which is no in our support scope. I will also add teams-app-dev tag to your thread. Thanks for your understanding!
