MultiVOIP Phonebooks
When a VoIP serves a PBX system, it’s important that the operation of
the VoIP be transparent to the telephone end user. That is, the VoIP
should not entail the dialing of extra digits to reach users elsewhere on
the network that the VoIP serves. On the contrary, VOIP service more
commonly reduces dialed digits by allowing users (served by PBXs in
facilities in distant cities) to dial their co-workers with 3-, 4-, or 5-digit
extensions as if they were in the same facility.
Furthermore, the setup of the VoIP generally should allow users to
make calls on a non-toll basis to any numbers accessible without toll by
users at all other locations on the VoIP system. Consider, for example,
a company with VOIP-equipped offices in New York, Miami, and Los
Angeles, each served by its own PBX. When the VOIP phone books are
set correctly, personnel in the Miami office should be able to make calls
without toll not only to the company’s offices in New York and Los
Angeles, but also to any number that’s local in those two cities.
To achieve transparency of the VoIP telephony system and to give full
access to all types of non-toll calls made possible by the VOIP system,
the VoIP administrator must properly configure the “Outbound” and
“Inbound” phone-books of each VoIP in the system.
The “Outbound” phonebook for a particular VoIP unit describes the
dialing sequences required for a call to originate locally (typically in a
PBX in a particular facility) and reach any of its possible destinations at
remote VoIP sites, including non-toll calls completed in the PSTN at the
remote site.
The “Inbound” phonebook for a particular VoIP unit describes the
dialing sequences required for a call to originate remotely from any
other VOIP sites in the system, and to terminate on that particular
VOIP.
Briefly stated, the MultiVOIP’s Outbound phonebook lists the phone stations
it can call; its Inbound phonebook describes the dialing sequences that can be
used to call that MultiVOIP and how those calls will be directed. (Of course,
the phone numbers are not literally “listed” individually, but are,
instead, described by rule.)
Consider two types of calls in the three-city system described above:
(1) calls originating from the Miami office and terminating in the New
York (Manhattan) office, and (2) calls originating from the Miami office
and terminating in New York City but off the company’s premises in an
