To call the Minneapolis/St. Paul area, a Baltimore employee must dial eleven
digits. (In this case, we are assuming that the Baltimore PBX does not require
an “8” or “9” to seize an outside phone line.)
If a Baltimore employee dials any phone number in the 612 area code, the call
will automatically be handled by the company’s voip system. Upon receiving
such a call, the Minneapolis voip will remove the digits “1612”. But before the
suburban-Minneapolis voip can complete the call to the PSTN of the
Minneapolis local calling area, it must dial “9” (to get an outside line from the
PBX) and then a comma (which denotes a pause to get a PSTN dial tone) and
then the 10-digit phone number which includes the area code (612 for the city
of Minneapolis; which is different than the area code of the suburb where the
PBX is actually located -- 763).
A similar sequence of events occurs when the Baltimore employee calls
number in the 651 and 952 area codes because number in both of these area
codes are local calls in the Minneapolis/St. Paul area.
The simplest case is a cal from Baltimore to a phone within the
Minneapolis/St. Paul area code where the company’s voip and PBX are
located, namely 763. In that case, that local voip removes 1763 and dials 9 to
direct the call to its local 7-digit PSTN.
Finally, consider the longest entry in the Minneapolis Inbound Phonebook,
“17637175. Note that the main phone number of the Minneapolis PBX is 763-
717-5170. The destination pattern 17637175 means that all calls to
Minneapolis employees will stay within the suburban Minneapolis PBX and
will not reach or be carried on the local PSTN.
