VoIP Training | Voice over IP Training Course

As VoIP goes mainstream and starts to supplant the traditional phone connections, understanding this technology becomes critical for all concerned with telecommunications and information technologies. With the confusing array of systems and applications that are now available, many mergers and acquisitions that have taken place, and the many new players that are in the marketplace – not to mention the protocols advancements that have occurred — VoIP is not an easy technology to grasp.

Today’s technology is limitless, and with evolving trends, Voice over Internet Protocol has been conceived and has changed the way that people communicate with one another. ENO offers VOIP training courses for Fortune 500 companies, small businesses and government agencies. Our training seminars are of the highest quality, specifically designed by experts in the respective field.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
