When the Silent/Tone Monitoring party goes on hook, monitoring is deactivated. If the Monitoring PIN was a requirement for the activation of Monitoring, the active "short" or "long" PIN is also deactivated and the message "Identification deleted" is displayed for digites with display. The ID card PIN is not deactivated.

If, however, the Monitoring PIN system parameter was not a requirement for Monitoring, the "long" PIN or the ID card PIN is not deactivated. The short PIN is deactivated as is usually done after one call.
