Cell Phone companies in Europe and the Far East are beginning to offer a ser-
vice in which a called party will be able to provide a personalized "ring
back." This personalized ring back could be melodies, voice messages, etc.
This service is called "personalized ring back" or PRB.
This creates a problem for voice and answering machine detection algo-
rithms. Because the PRB will appear as voice or music, there is no way of
recognizing it as a valid ring back signal, and it would normally be declared
as either live voice or as an answering machine.
Although primarily limited to cell phone users at the current time, it is
expected that this feature will eventually be offered to land line users as well.
It is also expected that this feature will be offered here in the USA.
The TSP500 has been modified to offer a mode of operation whereby voice
detection will not begin until "answer supervision" is detected (the called
party picks up the phone). Other call progress tones such as rings, busy, fast
busy, or SIT tones continue to be detected at anytime prior to "answer super-
vision" being received. It is only voice or answering machine detection that
will wait for supervision before being activated.
This should allow us to ignore any non-standard audio received prior to the
called party answering the phone.
Certain Telco announcements do not always have SIT tones associated with
them. If these type announcements are received without answer supervision,
they will be erroneously declared as "Ring No Answers." Previously they
would have been declared as answering machines or unknown SITS (if the
option to Check Supervision was turned on).
Telco announcements that have SIT tones at the tail end of the announcement
and do not provide supervision will be detected correctly. This was something
that was not always possible because voice detection always began prior to
answer supervision.
This feature can be turned On or Off as follows:
A new dialing rule keyword WAIT_FOR_SUPERVISION has been added.
WAIT_FOR _SUPERVISION 1 ! Wait for Supervision
before starting voice detection.
WAIT_FOR _SUPERVISION 0 ! Start voice detection
immediately after dial launch.
