It is normal for the device to reply 200 ok when the platform sends an invite request to play a video message from the data packet, but after the request, it can be seen that the device has not sent a stream. Then analyze from the data packet, after the normal request to play the video, the platform sent syn interaction information, which should be sent by the device actively.

Just change the udp protocol of the security video monitoring EasyGBS device to TCP passive, re-capture the packet and check that the device actively sends syn and then reply ack to send the flow normally.
