Abstracts assignment APA Style used. Kondisetty, Sudhakar (April 05, 2001). VoIP in your contact center - much more than cheap phone calls. [Electronic version]. Computer World. Retrieved on May 20, 2004, from web helps develop your CRM (customer relationship management) strategy and enlarge client loyalty, enhance operating competence and boost sales in addition to noticeable savings from eliminating long-distance tolls.

Call center systems will reach 30% of total VoIP revenues, which is projected to be $1.4 billion. The merging of PSTN voice and data replaces the telephone switch with IP based software, which simplifies infrastructure and reduces cost. An IP call center is both economical and easy to install. Companies with multiple call centers have these advantages are amplified. Rise in Internet use required companies to furnish call centers with ways to reply to the various ways customers call in to the center. Challenges for companies include providing a reliable yet familiar forum for customers not matter what means of communication they may use.

One solution is media blending software that merges Internet capabilities like wireless, e-mail, chat and video with the voice of sales and service representatives. A developed Voice over IP based CRM perform functions like how contacts are queued and routed, identify and segment customers based on value to business, integrate front and back office systems for consistent view, synchronizing key information, customer history, and business workflow.

Is your telephone system outdated?

[Electronic version]. Tech Soup. Retrieved on May 20, 2004, from web over IP started in the late 1990's due to likely savings from merging voice and data systems. Quality of service with IP protocol held back acceptance until discovery of new technology. Circuit-switch telephone calls require a direct connection where VOIP technology doesn't.

Voice data is converted and compressed into packets and sent to its destination. Packets may or may not take the same path. Applications for VOIP include the Internet telephone, LAN / WAN voice communication, FAX over IP, Unified messaging, and conferencing. Combining voice and data network, reducing long distance cost, and flexibility are all advantages for Voice Over IP. Disadvantages include Quality of service and lack of standardization among protocols. Quality of service issues include timely deliver of voice packets even though the IP standard wasn't developed with this in mind.

While these problems can be controlled in a LAN, the public Internet creates problems like packet loss, jitter and latency. Morris, Ray (1998). Voice Over IP Telephony: Sizzle or Steak? [Electronic version]. Retrieved on May 20, 2004, from web ht a / room 11/Loop Co / VOIP. html Is using IP to transport voice an advance in technology or just a marketing ploy?

Data networks are made up of links and nodes. Traffic is controlled at each node to assure data integrity. Also, traffic is controlled at the network level by network protocol. Most voice transmission within public networks are digital. Advantages of digital transmission include lack of noise interference and low maintenance. Circuit switched networks are better for voice communication because voice needs continuous employment.

Packet switching is prone to delays while network is busy and voice communication is highly sensitive to these delays. Circuit switched networks block new calls during busy times to uphold voice quality for calls previously established. Networks designed for data can handle addition of voice traffic but networks that carry mostly voice should not junk their composition. Data communication is growing 10 times faster than voice. Since IP protocol was designed to treat all traffic the same, many feel ATM is better suited to control voice.

First, ATM has a "classes of service" to enable voice to be prioritized over data. Second, ATM uses shorter length packets so big packets can't dominate bandwidth and slow the network. ATM is high-priced and not common so far. ATM is the steak and IP is the sizzle.
