they go out onto the local PSTN.
Essentially, all those calls come to the
receiving voip with a pattern
beginning w i th
1+area code
. The local
voip removes those four digits
becau se t h ey ar en’ t need ed w hen
dialing locally. The local voip
attaches a “ 9” at the beginning of the
number t o get an outside line. The
PBX then completes the call to the
PSTN .
The second
Inbound
Phonebo ok ent r y
(8 digits) is for receiving calls from
com p an y em pl oy ees i n t h e ot h er t w o
ci t i es. The ou t-of -t o w n em p l oy ee
si mp l y d i al s 3 d i gi t s. The f i r st of t he
three digits is uniquely used at each
site and so act s as a desti nat i on
p at t ern (Boi se extensions ar e 7xx,
Sant a Fe ext en si on s 2xx, Fl agst aff
extensions 6xx).
As the remote voip sends out the call,
it automatically attaches all of the
foregoing digits that would normally
have to be dialed using the PSTN.
The l ocal (r ecei vi ng) v oi p sees the
extended pattern in its Inbound
Phonebook and so strips off the long
t el l tal e pat t er n of di gi t s need ed f or 3-
digit calling. It must finally add back
the last digit before handing the call
to the PBX, which completes the call
t o a speci f i c ext en si on.
