Below we have outlined the major reasons why more corporate users are considering VoIP based systems:

1. Call Cost Reduction.

The lower cost of calls on VoIP systems over traditional PSTN networks is the first advantage people think of when switching to a VoIP based system. Essentially phone calls made over existing IP circuits are free, save for the cost of the equipment required to make that call. Enterprises can cut their telecommunications costs with VoIP in two ways:

1a. Calls over the company IP network.

Most multi-site companies have linked their computer systems over an IP wide area network (WAN). VoIP technology uses this network to carry voice calls. Companies can install specialized IP phone systems, or IP gateways such as VegaStream to connect existing phone equipment to the WAN. This removes the call charges and, equally significantly, the rental charges on the telephone lines.

1b. Using and Internet Telephony Service Provider (ITSP)
