Configuring Video Recording Synchronization
If you also want to record the video stream of audio-video calls, you need to configure a video synchronization timeout. When the video stream is also recorded, the device operates as follows:
|
1.
|
Once the call is answered by the called UA (i.e., connected), the UAs' audio streams are connected and the device sends a SIP INVITE to the SRS. However, for correct video synchronization, the UAs' video streams are not yet connected at this stage. |
|
2.
|
When a SIP 200 OK response is received from the SRS and the UAs' ports have been negotiated, the device connects all video streams - the UAs' video stream and the recorded video stream (the recorded audio stream is also sent to the SRS at this stage). However, if the 200 OK from the SRS is not received within a user-defined video synchronization timeout, the device connects the video stream between the UAs. |
