What I Want to See from Switchvox at Astricon

Posted by Randy Kremlacek on Oct 19, 2012 10:22:00 AM


Georgia on My Mind

This coming week, the world’s largest open source telephony conference, known as Astricon, convenes in Atlanta Georgia. Digium, the creator of Asterisk and developer of Switchvox, hosts this convention that attracts telecom coders, commercial PBX developers and telecommunications pundits from around the world.

Also, attending is me from little ol’ Teledynamic Communications. I’m very proud that this is my third year serving on the Digium Partner Advisory Council.

Asterisk or Switchvox - Which is Right For You?

Posted by Randy Kremlacek on Oct 12, 2012 4:49:00 PM

What's the Difference Between Asterisk and Switchvox?

As the Bay Area's leading Digium Switchvox Reseller, we get asked this question a lot. 

I like how Digium portrays the difference: Asterisk is an Engine, Switchvox is a Vehicle.

While both products fit into the larger universe of telecommunications technologies, they have very different purposes and are geared towards very different audiences.

In this multiple part series, I’m exploring the four evils that are the curse of high-quality Virtual PBX: Bandwidth, Jitter, Packet loss and Latency.

In this final installment, we talk about Bandwidth.

What is Bandwidth?

Bandwidth is often interpreted to be the speed that data passes through a given circuit. It's commonly measured in Kilo (thousand), Mega (Million) or Giga (Billion) bits per second.

The 4 Horseman of the Virtual PBX Apocalypse Part 3: Jitter

Posted by Randy Kremlacek on Oct 2, 2012 3:14:00 PM

In this multiple part series, I’m exploring the four evils that are the curse of high-quality Virtual PBX: Bandwidth, jitter, packet loss and latency. Today’s subject is jitter.

What is Jitter?

Jitter is a little bit hard to explain. Remember when we talked about how latency is the measure of packet delays over a VoIP network? Jitter is just the variation in the time between packets arriving. In other words, it's the variation in latency.

Each IP packet comes with a sequence number and time stamp in its header. This is how the VoIP equipment knows in what order they need to be re-assembled and when they were produced. A connection is experiencing jitter if many of the packets come in at varying differences between packet time stamps.

Posted by Randy Kremlacek on Sep 15, 2012 9:01:00 AM

Are Internet Connections Just a Commodity?

Many people think Internet access is a generic, commodity product with no differentiating features between one provider and the next.

This is simply not true, especially when it comes to providing quality transport of voice traffic.

What You Need to Know About QoS on Virtual VoIP PBX

Posted by Randy Kremlacek on Sep 12, 2012 6:08:00 AM

What is QoS?

QoS stands for Quality of Service. It's a term you'll hear when people are talking about data network traffic optimization for voice. QoS is set of protocols and rules built into LAN routers and sometimes WAN switches, to prioritize network traffic and help ensure that the "most important" data gets through the network as quickly as possible.
