Public TelephoneFrom Tele Technology:

There is a lot of equipment in my office that cause me grief, pain and suffering.

Like for instance, I have this printer.  A mammoth, $4000 dollar printer that I picked up from a local guy on Craigs List for like… $400.  A steal!

My buddy, a guy named Patrick actually found it for me.  He called me and said “Hey!  I found the most awesome printer for you.. you know.. the one you have been looking for… a 4 color laser jet, right??  Well THIS is a steal, and a great printer, and you should buy it.”

So I did.  The two of us damn near broke our backs to move this 200 pound mammoth to the second floor platform that is my main sales office.  I mean this thing is HEAVY!

We plugged it in, and the first thing I realized is… “we need another network hub for this thing to work.”

Much more…

From TeleDynamic Communications:

Today, we’ll discuss latency.

What is Latency?

VoIP latency is the delay between when the data packets of your voice conversation is sent and when it’s received.
For most regular data like your email or when your downloading a webpage, a few microseconds of latency doesn’t impact your user experience. It doesn’t really matter that an email arrives a quarter of a second later or a website takes a moment longer to load.

Voice is Different

But voice is different. Voice is real time, for real. 
When you speak, you expect to be heard immediately. A delay of as a little as two tenths of a second, makes a voice conversation extremely challenging. The industry standard for acceptable latency for a Business VoIP conversation is only 120 milliseconds. This is less time than the blink of an eye at around 140 milliseconds!
As a way of comparison, an old fashioned analog line has a latency of about 60 milliseconds and phone calls between cell phones can be up to 150 milliseconds. Cell phones have “trained” users that noticeable voice latency is a fact of modern life.

What are the Factors That Affect Latency?

There are really 5 primary factors that affect latency in any business VoIP connection:
