VoIP (Voice over Internet Protocol) is clearly becoming the best telephony solution for small business. The low cost of VoIP is its biggest attraction. Business VoIP services are significantly less expensive than traditional phone services. You have much less hardware to buy or lease; in fact, many hosted services require no new hardware investment at all. If you do need hardware, it�s typically based on standardized technologies such as SIP, as opposed to proprietary products that tie you to a particular service provider. Monthly subscription fees are lower, as well.
