Yesterday, I was helping a friend solve some quality issues with his Vonage VoIP line. In essence, he had bandwidth issues: As soon as he checked his email or opened a web page, his voice conversation would start dropping. I could not do too much about that, because he rents some office space from a local business owner where he shares the owners bandwidth with 3-4 other people.
Unable to change the router (no $$$ and no ownership), I decided to see what the Netopia 3347 could do. QoS? Traffic Shaper? no, something called Differentiated Services (DiffServ).
It can be found under the ‘expert mode’, Advanced -> Differentiated Services
Not knowing the IP’s of Vonage, I started playing with the local IP of the Vonage box. I ended up with the following:
This was enough to be able to watch a high-def Youtube vid without significant quality loss on the phone…
I cannot imagine that I am the first person that wants to do this. However, in searching for Vonage / Netopia / QOS, no clear instructions showed up. If it help you, out there, here you go!
For more information on what Traffic Shaping and QoS is and how to configure it on routers that support more complete functionality, see http://mollien.net/index.php?main=articles&article_id=24
Sizing up Connected Real Estate – Does size really matter?
Today, I’d like to explore how to size the connectivity aspect when exploring the decision to offer (or just use) Connected Real Estate for a Real Estate Project.
Defining the needs of the target market
When considering Connected Real Estate, it is important to understand what the target market is and what their requirements for technology are, now and in the future. Are they expected to be international companies that can be expected to rely a lot on international communications? These companies are likely to be interested in VoIP (Digital Telephony) and video conferencing. Are they

Specialization is for insects.
One of the things that I have always seen as a strong point, is being a Jack of all Trades. It has always surprised me how society in the US is determined to pigeonhole who you are and what you do - If I talk about my experience or drop my resume at an employers desk, there is often confusion about where I fit in.
In other parts of the world it is normal that an IT guy has knowledge of everything including the kitchen sink, as long as it has an IP address. But in the US, specialism is the norm.
I was in the fortunate situation earlier this week, to play around with the Cisco Cuis. Unfortunately, the device was not fully connected yet but it is a very interesting development.
The Cisco Cius is an “IP-based communications end-point”. Blah. What this essentially means is that Cisco sees the device as a phone first, and everything else later.
