24-Channel Digital VoIP (MVP2410)

One Common Situation

Voip Example. This company has offices in three different cities. The PBX units all operate alike. Notably, they all give access to outside lines using

“9.” They all are ‘smart’ enough to identify voip calls without using a special access digit (“ 8” is used in some systems). Finally, the system operates so that employees in any office can dial employees in any other office using only three digits. Here are the phonebooks needed for that system.

Inbound Phonebook

Each Inbound Phonebook contains two entries. The first entry (4 digits) specifies how incoming calls 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 outside 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 and so acts as a destination pattern (Boise extensions are 7xx, Santa Fe extensions 2xx, Flagstaff 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 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 directs the call to the 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.
