Inbound Phonebook Discussion
Outbound Phonebook Discussion
Each Inbound Phonebook contains two
entries. The first entry (4 digits) specifies
how incoming cal ls from the other voip
sites will be handled if they go out onto
the local PSTN. Essentially, all those calls
come to the receiving voip with a pattern
beginning with
1+area code
. The local
voip removes those four digits because
they aren’t needed when dialing locally.
The local voip attaches a “9” at the
beginning of the number to get an outsid e
line. The PBX then completes the call to
the PSTN.
The second Inbound Phonebook entry (8
digits) is for receiving calls from company
employees in the other two cities. The
out-of-town employee simply dials 3
digits.
The first of the three digits is uniquely
used at each site an d so acts as a
destination pattern (Boise extensions are
7xx, Santa Fe extensions 2xx, Flagstaff
extensions 6xx).
As the remote voip sends o ut the call, it
automatically attaches all of the foregoing
digits that would normally have to be
dialed using the PSTN.
The local (receiving) voip sees the
extended pattern in its Inbound
Phonebook and so strips off the long
telltale pattern of digits needed for 3-digit
calling. It must finally add back the last
digit before handing the call to the PBX,
which completes the call to a specific
extension.
Each Outbound Phonebook contains two
pairs of entries, two entries for each
remote site. Whenever an out-of-town
employee dials a 12-digit number
beginning with the listed 5-digit
destination pattern (9+1+area code) of
another company location, the PBX hands
the call to the voip system. The local voip
strips off the “9” and dir ects the call to th e
IP address of the remote voip. The
remote voip receives the call and hands it
to its PBX. The PBX then completes the
call to the PSTN.
The one-digit Outbound destination patterns
pertain to 3-digit calling between company
employees.
