"It's Time To Take a Look at SIP"
Maybe IP Centrex isn't your cup of tea, but you still want simple-to-use packetized voice. There are several options available, from companies such as CBeyond and Vonage, that place an IAD (integrated access device) at the customer premises. Analog handsets are then connected to the IAD, which packetizes the call and places it on a data network. These services are designed for companies that have five to 100 employees and want to continue using analog phones while enjoying the convenience of IP. CBeyond offers several business plans for data, voice, e-mail and conference calling.
Vonage, which primarily serves the residential market, says it is adding more business customers each month.
There are two predominant financial drivers for companies moving to IP Centrex services: increased user productivity, thanks to advanced features such as smart redirection of calls, easy conferencing and a single pot of e-mail, fax and voicemail messages; and lower support costs due to simplifying phone moves, adds and changes. In addition, some conventional benefits of outsourcing apply: freeing your people and capital to build the business rather than maintain a PBX; a fixed monthly cost; scalability; and no worries that pricey hardware will become outdated.
