Customer is not using our JS sdk for frontend, instead they are using third-party SDK.

In December, there similar issue. Recordings ware just stopping after 1-2 sec, not 16 mins.
We had a meeting with customer, debugging theirs code for a bit, we figured out why audio stops, and provided hack-fix solution. But it seams same issue occured again, just this time after sometime, not instantly.

---

• Debug and provided bandage fix (in December)
• Recommended customer to switch to our JS SDK to avoid those kinds of problems (in December)
• Recommended customer to set dropWebRTCIngestIfNoPacketReceived: true as another immediate 'bandage' so that streams get killed and can be restarted, in case packets stop being received, instead of producing corrupted recordings. (in January)
