Let’s looks at a detailed example of how this happens. Referencing Figure 1, we see the following:

1. Call being originated from the PSTN - This call transits over the PSTN to its designated rate center.
2. TDM/IP Demarc - Once the call passes through the rate center, it is backhauled to a wholesale VoIP demarcation point and sent into the IP domain.
3. Call Presented to BandTel - From the demark, the call is routed to BandTel’s switching point of presence (POP).
4. Call Analyzed and Routed - At the BandTel POP, the call is analyzed and GNP routing logic is executed via the BandTel ENUM server.
5. Call Routed to destination - The BandTel “ENUM Server”™ forwards the call on to its final destination.
6. Ring Ring - The VoIP phone rings, is answered, the parties are connected, Real-Time Protocol (RTP) data flows, and talking begins.

The Value to the Enterprise
With respect to the enterprise, the GNP concept offers major advantages on several fronts. First and foremost is of course removing the concept of “local” and replacing that with “global.” The corporate IT manger is then free to point inbound DID and 800 telephone numbers to any VoIP telephony switching device in the enterprise and see results instantly. This allows total freedom of operations as it pertains to geographic location and relocation. There are no longer any “local” limitations. All terminations are globally portable and dynamically user defined.

Another application that results from BandTel’s GNP is Global Number Translation (GNT™) This BandTel service allows an end user to order any DID or 800 number from any geographic market supported by BandTel, and have that number forwarded to any other number in the PSTN (e.g., 1+, 011+, or 800).

In that way, GNT™ allows an enterprise to establish a local presence in any market but then backhaul it to any PSTN termination point with no restrictions. Further, routing changes on the GNT setup can by made simply by submitting a request to BandTel support, and then seeing the translation change order filled and operational in a matter of hours.

Conclusions
VoIP technology, and specifically SIP with BandTel GNP services, is rendering fixed address-physical location ties of an end telephony station device unnecessary and irrelevant. In so doing, it solves major issues for enterprise telephony system deployments. This includes:

• Immediate On-Net cost savings - GNP unifies the dispersed enterprise by leveraging the flexibility of IP, and thus allowing huge savings on interoffice communications.
• Relocation now trivial - VoIP with GNP solves the enterprise dilemma of relocation and allocation of end station addressing, turning what was a totally fixed static model into one that is user definable, configurable, and totally dynamic.
• Enterprise scaling simplified - GNP allows resizing of an enterprise to take place with
  little or no inconvenience or disruption of telephony services. Facilities can be added or removed and telephony needs scaled immediately to handle new enterprise footprints.
• Local competition realized - GNP finally provides true competition for local access, irregardless of is the local exchange telephone company physically in the Enterprise’s geographical market space.
