The advantages of Primary Rate Interface (PRI) service and Session Initiation Protocol (SIP) can be debated.

PRI uses a circuit switched model for voice call among people located in different locations.

How Does It Work?

Multiple users can access these 23 channels within …

Revolabs conference phones for distance learning

Note: This is a guest post by Victoria Zona, Senior Channel Sales Manager, Revolabs

Academic institutions are all adding programs to accommodate remote students and are now offering on-line degrees.

To save money, many corporations are remotely training branch office employees on the policies and procedures bringing distance learning to corporate workplaces.

Clear Audio Maintains Focus, Increases Comprehension, Reduces Fatigue

Many times the voice quality in remote learning environments is unintelligible. Poor sound quality makes it difficult for the student to understand the material presented, and reduces their active participation.

Our industry has made great strides to improve video quality during distance learning sessions, but crystal-clear audio is even more …

I’ve experienced audio fatigue, and I’m sure many of you have as well when you can’t understand the person at the other end of the line due to more than one person talking at once or background noise from a terrible audio device.


Look for products that have ultra-wideband technology for the most intelligible speech, automatic gain control, and noise suppression
