Building the VOIP Dialing Plan

MultiVOIP provides single stage dialing by utilizing a Uniform Dialing Plan that is consistent with both

the PBX and the E.164 (PSTN) standard numbering plan. This means placing calls is like using your

existing phone system, no user training is needed.

In order to accomplish this, MultiVOIP utilizes an Inbound and Outbound phonebook. In our company

example, the system allows employees in any of ce to dial employees in any other of ce using only

three digits. The following is a worksheet used to layout this company’s dialing plan.

A more sophisticated phonebook setup can be created that requires an “intelligent” PBX and the

MultiVOIP gateway to automatically append and strip digits. So, for example, when an employee dials

another remote company location using a standard 12-digit number, the PBX would know to hand

that call to the MultiVOIP gateway. MultiVOIP, in turn, would strip the unnecessary 5-digit destination

pattern (9+1+area code) and direct the call to the IP address of the remote MultiVOIP. For details on this

type of dialing plan, refer to the user’s guide.
