Chapter 8. VoIP Networking > VoIP SOHO Network Application Configurations

VoIP SOHO Network Application Configurations

Both home-office and small-office LANs can benefit from VoIP products and services. Several of these configurations are examined to illustrate the products and benefits. These product configurations can vary from simple devices that connect analog PSTN telephones to the Internet to reduce long-distance charges, to more sophisticated small-office PBX systems that connect remote offices into the central-office PBX using VoIP and that can provide reduced long-distance costs by routing long distance and international calls over the Internet or private IP networks at reduced rates. The primary benefits of these VoIP products and services are reduced long-distance costs, centralized telephony operation and monitoring for remote workers, unified data and voice network wiring and operation, and cheaper telecommunications components such as PBX systems.

Home-Office Networks

Several products are targeted at small home-office LANs. A low-end product permits routing telephone calls across the Internet with the goal of saving costs. This French product requires that both the origination and termination calling points have a unit installed. The call is then initiated over the PSTN. When the terminating phone is answered, a button on the product is pushed and the product then reroutes the call over the Internet where the parties can talk toll free for an extended time period. Both originating and terminating stations must have their device set up to place and receive calls from a local ISP to enable the call to be rerouted across the Internet. The call must be initiated using the PSTN to ensure that the call terminating party is available to answer the phone. The device must also compress the voice into a small data stream because digital transmission is limited to 53 Kbps on a good day. However good voice quality today is realized with transmission speeds of a little as 9,600 bps. The coder/decoder (codec) used determines the compression and voice quality over the Internet.
