Configuring the OneBox Dialing Plans
Both Faxtext and fax messaging use dialing plans that let the telephony server validate
telephone numbers entered by outside callers and subscribers when they want to
transmit a fax. For example, if a caller in the United States enters only six digits for a
telephone number, the telephony server can look up the number on the dialing plan,
then prompt the caller that this number is invalid. The caller can then enter a correct
seven-digit telephone number.
The dialing plan also gives the telephony server dialing instructions for telephone
numbers and indicates the call type: international, long distance, local, or extension.
With the information from the dialing plan, the server can correctly place calls to any
telephone number.
The telephony server uses the call type information it receives from the dialing plan to
determine whether or not the call is allowed. For example, if a subscriber sends a fax to
a long-distance number, the server uses the dialing plan to determine the call type. It
then checks the subscriber’s mailbox to see if the subscriber has long-distance callouts
allowed. If they are allowed, it places the call; if not, it advises the subscriber that the
call is not allowed.
The fax server uses a similar dialing plan for outgoing calls that it originates itself, such
as outbound faxes from subscribers. Using a sophisticated set of routing rules, the fax
server can calculate the least costly time of day to send a low-priority or medium-
priority fax. If a network has more than one fax server, the dialing plans of the fax
servers can be coordinated to share the total load of outgoing faxes.
Note Each telephony server interacts directly with only one fax server platform. In a
system involving multiple fax servers and only one telephony server, the fax server that
interacts with the telephony server can distribute outgoing faxes to the other fax servers
to balance outgoing traffic between all of them. Incoming faxes originating from
OneBox may only be passed to a single fax server.
When setting up the fax server’s dialing plan, keep in mind that OneBox output to the
fax server must be dealt with, as must client-generated telephone numbers for outgoing
calls (for example, adding 9 to the beginning of local or long-distance calls). Be sure to
coordinate the two dialing plans to work together.
To configure the telephony server’s dialing plan, refer to the OneBox Administration
utility’s online help. The RightFax Administration Guide contains the corresponding
instructions for setting up the fax server’s dialing plan.
Important The telephone system at your site may offer sophisticated least-cost routing
features of its own. If so, you may want to use your OneBox dialing plans only to
validate extension, local, and long-distance numbers. To provide least cost
routing, set up your telephone system so that it processes all outbound calls and
faxes according to its dialing plan.
