9. Naive caller
« Callers are accustomed to being answered normally within 10s and the majority abandon calls that are not
answeed within 45s »
It is « normal » to set the number of rings at between 1 to 5 rings before the answering machine responds
The machine is already preset for a plug and play mode.
« If the intention is to delay answer so that normal voice callers would abandon the call before the non-voice
TE answered, then delay should be at least 45s ».
It is helpful to include with the statement of the answering telephone number the exchange name or
international code, and announcements must be suitable for the purpose for which they are intended. The
announcement should also start within 3s of answering.
Paytone may be received after answering calls from some types of payphones and may persist for up to 13s.
Answering announcements should be constructed so as to ensure that an answering announcement
containing the identity of the called line and, where appropriate, the invitation to record, will be heard by
the callers after paytone has ceased.
