There is interference on the telephone line that is connected to the modem.
Cause It might be due to interference from a power source. monitor, printer, or other computer cables.
Solution Try moving the telephone line away from any power source, monitor, printer, and other computer cables.
The modem or communications software fails to detect that the remote user has hung up.
Cause | The modem and communications software relies on the dial tone, busy tone, or a |
| period or silence to detect that a remote user has hung up. This detection may fail |
| due to one of the following reasons: |
| ❑ Your local telephone system does not generate the dial or busy tone when the |
| remote user hangs up. |
| ❑ The period of silence the modem or communications software uses to detect |
| that the remote user has hung up, is not long enough. |
| ❑ The modem or communications software cannot detect an unusual dial or |
| busy tone. For example, if you are connecting to a PABX system, the dial or |
| busy tone generated is different from the usual dial or busy tone. |
Solution | You can prompt the user to respond. |
| This may however result in a long delay before the communications software |
| responds to the remote user hanging up. To minimize this delay, try to modify the |
| following settings: |
| ❑ Voice message recording time |
| ❑ The number of prompts |
| ❑ The time to wait for a response after prompting |
