Using callback

If a called internal connection is engaged or nobody answers, a callback can be
requested. This is also the case for external calls via telephone exchanges.
Repeated call attempts can thereby be avoided.
You receive the callback
• as soon as the other party's line becomes free,
• as soon as the party who did not reply has held another conversation.
If configured (ask relevant Administrator), all callback requests are auto-
matically deleted overnight.
