Other properties
The 2025/2045 and A150/300 systems have three parallel Courtesy channels; the
2065 system, six.
• If another call occurs during a recorded announcement, the second call is
switched to Courtesy via a second channel once the delay has expired.
• If all channels of a group are busy, the next caller is put on a hold position. He
will obtain the ring-back tone until a channel once again becomes free or until
he can be synchronised with the start of a busy channel.
• If an endless loop is defined for a Courtesy announcement, callers on several
Courtesy channels can be synchronized with the same announcement text on
the same channel. This frees us channels for new callers. The requirement is that
the pauses for the same step overlap chronologically while the announcement
sequence is played back.
The Courtesy service is also available if:
• the external call's destination is a PISN user in a QSIG network who has activated
the Courtesy service locally in his node.
• an internal user has diverted to a PISN user in a QSIG network who has activated
the Courtesy service locally in his node.
The call routing, the delay setting, the definition of the sequences and their assign-
ment to the switch positions can only be carried out by the Installer in the system
configuration.
