Factors To Consider
High definition voice is clearer than older VoIP technologies and traditional landline voice because it delivers at least twice the sound range, about 7 kHz. It’s now a standard feature in business-class IP phones, including the affordable Cisco SPA 300 Series and 500 Series IP phones. HD voice quality is especially important for international, technical, or long conversations; conference calls; and speakerphone use. Most businesses usually need about eight or more lines for the front desk or a group assistant. A single-line phone may be ideal for backroom and warehouse locations; the new Cisco SPA 301 is a basic one-line phone priced under $100. IP phones connect to your data network through Ethernet cabling or Wi-Fi and some also receive power over Ethernet. Wi-Fi support is a must-have for mobile users who need the phone while moving around your site.

Features
IP phones offer features such as speakerphone, caller ID, call forwarding, and conferencing. There are certain models that offer certain features not found on traditional phones. They allow you to operate the IP phone seamlessly between cellular and VoIP services. You can answer calls that started on a Smartphone, connect through Bluetooth, and import your Smartphone address book. Easily unify all your messages; voicemail, email, and faxes, into one inbox so that you can retrieve and respond faster and more easily. Increase the productivity of employees by enabling them to use the web and XML documents directly on their phone.
You can give employees access to information on your data network, such as customer records, order status, and schedules. Some IP phones can monitor video from your IP surveillance cameras, play MP3s, and display digital photos. No IP phone is compatible with all VoIP systems, due primarily to differences in their VoIP protocols. The Session Initiation Protocol (SIP) is the most widespread. Some IP phones support both SIP and the Smart Phone control Protocol (SPCP) to help ensure interoperability in both modes. The VoIP system options include a hosted VoIP or Centrex service that you contract from a service provider and an onsite VoIP system that you own or lease.
There is encryption of voice, password protection for signalling and configuration data, and Wi-Fi security features protect against unauthorized use. An embedded virtual private network (VPN) client on your remote users’ IP phone allows them to securely connect to your network and make calls over the Internet. IP phones that are designed to interoperate with one another and your VoIP system should be the easiest to set up, move, upgrade, and manage.
