MULTI-OPERATOR
With the ARS mechanisms, this environment enables:
- use of the cheapest operator to call a correspondent.
- overflowing through the other operator when the cheapest one is unavailable.
INDIRECT OPERATOR
This environment makes it possible to redirect calls to operators offering attractive rates, for interna-
tional calls for example.
Depending on the analysis of the requested number, the ARS automatically redirects the call, transpa-
rently for the user, to another indirect substitution network and then retransmits the destination number
as follows:
- seizure of a line in the network of the main operator
- dialing the access code or the number of the indirect operator
- waiting for an intermediary tone (or pause)
- switching into transparent MF dialing
- optional transmission of the account code (waiting for a 2nd tone or pause)
- waiting for a second intermediary tone (or pause)
- dialing the destination call number
