How to solve the busy line of building intercom

The solution to the busy problem of building walkie-talkies is as follows:

1. Wait a minute: Maybe someone else is talking on the intercom. Wait a while, and then try to connect.

2. Try calling again: After waiting for a period of time, dial the number of the intercom again to see if you can connect successfully.

3. Check the calling channel: Make sure that the internal communication channel you are using is set correctly. Maybe your channel is used by someone else. Please try switching to another channel or contact the administrator for more information.

4. Restart the walkie-talkie: Sometimes the walkie-talkie may fail or get stuck. Try restarting the intercom, and then try connecting again.

5. Check the signal strength: the walkie-talkie needs enough signal strength to work normally. Make sure the signal in your area is good, and avoid obstacles or other interference factors from affecting the signal. Building walkie-talkie is a kind of equipment used for internal communication in buildings, which is usually provided and managed by building management departments or property management companies. Its function is to facilitate voice communication among residents, employees or visitors in the building.
