Phonebook Examples

The following example demonstrates how Outbound and Inbound PhoneBook entries work in a situation of multiple area codes (as in the Minneapolis metro area). This example also illustrates that MVPFXS voips allow remote callers access only to specific phone stations connected to the MVPFXS voip and do not allow remote callers access to the local PSTN in which the MVPFXS unit is located. Consider a company with offices in Minneapolis and Baltimore. The system depicted is SIP-only. In the Minneapolis office, an MVPFX2-8 unit is used and it affords both FXS and FXO interfaces. By contrast, in the Baltimore office, an MVPFXS-24 voip is used adn it offers the FXS interface only.

2 Site Example

Notice first the area code situation in those two cities: Minneapolis’s local calling area consists of multiple adjacent area codes; Baltimore’s local calling area consists of a base area code plus an overlay area code area code 443), but, since the voip used in Baltimore is FXS-only, it does not offer access to the local PSTN. That is, Minneapolis voip callers can call phone stations in the Baltimore office only; they cannot call into the 410 or 443 area codes using the voip system.
