Matrix ETERNITY NE System Manual 717
• The record of the outgoing call is stored in the RCOC Table, only if the same record does not already exist
in the database.
• Each entry is kept for the duration of the RCOC Record Delete Timer (programmable; default: 999
minutes). Whenever a record is stored in the RCOC database, the Record Delete Timer for that entry is
activated. On the expiry of the Timer, the entry is deleted by the system.
• Each record is deleted from the database either after the call is returned or on expiry of the Record Delete
Timer.
• The RCOC database remains unaffected during power outages.
• In case of Call Transfer, RCOC will be set for the extension which made the call on the trunk.
• The Ring Back Tone Timer is common to all internal calls; calls made from one extension will ring on the
destination extension till the end of this timer. Change in the Ring Back Tone Timer for RCOC returned
calls on original caller's extension will also be applied on Ring Back Tone Timer for all internal calls. So,
program this Timer taking this into consideration.
• Persons using DISA must be informed about RCOC feature access code ** and how to use this feature
when in DISA mode.
