The demo is running on two mobile phones, but why can't they display the images of each other?

Make sure that the two mobile phones use different UserIDs. With TRTC, you cannot use the same UserID on two devices simultaneously unless the SDKAppIDs are different.

What firewall restrictions does TRTC face?

The SDK uses the UDP protocol for audio/video transmission and therefore cannot be used in office networks that block UDP. If you encounter such a problem, see How to Deal with Firewall Restrictions to troubleshoot the issue.
