Description
Hi there! We recently developed a Video SDK videoconference solution, and we are now “battling” with our customers to make them authorize all the ports required by zoom to work. We did manage to prove those are indeed necessary, as by blocking ports 8801-8810 locally we cannot succesfully connect to any video class.
However, we were super surprised to find out that the demo app at Zoom Video SDK UI toolkit DOES indeed work with no problems with these ports blocked.
So my question: what are those ports for? And, can we set some connection attributes to make them optional in our application as well, so that users can connect even with those ports blocked?
What ports 8801-8810 are for, and can we skip them?
During the media stream exchange, we attempt to use UDP for faster transmission, which utilizes ports 8801-8810, especially in mobile platforms or when audio_compatible_mode is enabled.
We recently deployed a fallback solution for port 443; when ports 8801-8810 are blocked, TCP transmission will be used over port 443.
Hey Vic,
thank you so much for your response! Do you happen to know when you did release this fallback? Just to cross this data with our customer reports complaining about having firewall issues.
To my knowledge we do not have any extra flag enabled, so we should just stop receiving complaints after your patch, isn’t it? Or is there anything specific to turn this on, aside obviously from upgrading to the latest version of the Zoom Video SDK?
Thanks again
Matteo
