Enterprise Solutions: Long Distance Consolidation Application Note

From Quintum Technologies, Inc.

Companies with multiple offices typically maintain separate long distance service for each location. This can be costly, since smaller offices can't achieve the volume-based efficiency of a larger office with T1 access or greater to a telecom service provider's network. A more cost-efficient alternative is to have smaller remote offices place all of their long distance calls through the main office's trunk lines. This allows the company to have all of its calls billed at the lowest possible rate. Even a reduction of a few cents can result in thousands of dollars of savings per month for remote offices with heavy long distance utilization. The best way to perform this long distance consolidation is by routing voice calls from remote offices to the headquarters PBX over existing IP data links. This allows the calls to be routed without incremental costs that would cut into the savings achieved through consolidation. The use of VoIP also allows calls between offices to bypass the PSTN - making them virtually free.

Products & Services
Network Equipment
Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. In addition to device type, network equipment is defined by protocol (e.g., Ethernet).
VoIP and IP Telephony
VoIP and IP telephony allows PC users to make phone calls over the Internet or other packet networks via gateways and standard telephones.
Network Gateways
Network gateways interconnect networks with different, incompatible communication protocols. They perform a Layer-7 protocol-conversion to translate one set of protocols into another (for example, from TCP/IP to SNA or from TCP/IP to X.25).
Network Routers
Network routers are protocol-dependent devices that connect subnetworks, or that break down a large network into smaller subnetworks.
Network Firewalls
Network firewalls protect computer networks against unauthorized use or attack. They permit or deny access to private network devices and applications, and represent an important part of an organization's overall security policy. Firewalls may be software applications, hardware devices (such as routers), or a combination of both. They include turnkey products that are relatively easy to install as well as complex, multi-layer installations that require the expertise of a certified network administrator.
