http://blog.voipspear.com All about QoS testing with VoIP Spear. Tue, 18 May 2010 01:17:50 +0000 http://backend.userland.com/rss092 en VoIP Spear has always included the ability to calculate MOS using the big three codecs of VoIP: G.711, G.723, and G.729.  We've recently added support for GSM, G.722, Speex, and iLBC. VoIP Spear uses the E-Model of computation for estimating MOS from network statistics like packet loss, latency, and jitter.  In ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/WR_ZJVcU3To" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/WR_ZJVcU3To/ http://blog.voipspear.com/?p=63 It's not news that VoIP is becoming more and more mainstream all the time, but it sometimes amazes me how far it's come.  I first started up a VoIP company about 9 years ago and VoIP was so far out on the fringes that we would never use that term ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/eDLUEspc9OY" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/eDLUEspc9OY/ http://blog.voipspear.com/?p=60 A while back, I noticed a nice little feature about VoIP Spear at VoIP Resources.  It's flattering to see a positive review like this. We're especially pleased that the author of the article really seems to get VoIP Spear.  She starts off by describing VoIP QoS problems at a high level.  ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/3wCWzdqRzTc" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/3wCWzdqRzTc/ http://blog.voipspear.com/?p=56 My family and I are on holiday in Croatia right now.  We're staying in a bungalow on the Adriatic Sea in a little town called Brodarica and it's been very hot (35°C or 95°F).  As I type this, I'm looking onto a peaceful morning on the Mediterranean.  There's boats sailing ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/c34CrTi8dDo" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/c34CrTi8dDo/ http://blog.voipspear.com/?p=53 Just a quick posting to tell you that we've replaced our "North America: North" server.  It's been giving us problems of late so we decided the best solution was to retire it.  The new server is on the East Coast and we're pretty happy about that -- we now have ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/OpMo5cxOLdk" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/OpMo5cxOLdk/ http://blog.voipspear.com/?p=51 We're now offering pricing discounts for customers who pre-pay for multiple months.  We've been planing this for a while but it wasn't until recently that we actually had the time to implement it. Take a look at the discounts below.  We wanted to get pretty aggressive with the discount on 1 ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/fxF6GyqkIQU" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/fxF6GyqkIQU/ http://blog.voipspear.com/?p=47 The VoIP Spear API is ready at last.  It's pretty easy to use, though you can judge for yourself after reading the instructions.  The API is RESTful meaning that it's lightweight and easy to learn.  I'd imagine it's easier to learn a RESTful API rather than one based on SOAP ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/pmlLGUM788Q" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/pmlLGUM788Q/ http://blog.voipspear.com/?p=45 It's been two months since we launched VoIP Spear and we've learned alot in this time.  New users are signing up every day and it's exciting to see people all over the world using the service.  The first thing I do each morning (and, indeed, several times throughout the day) ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/V7Ctpa3mEII" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/V7Ctpa3mEII/ http://blog.voipspear.com/?p=21 VoIP Spear servers work by pinging our users' endpoints.  Ping is a nearly ubiquitous network tool that is used to test whether or not a computer/device is reachable across the Internet. One problem with using ping is that ping uses the ICMP protocol while VoIP uses UDP.  It was for this ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/Twa9Jmuokz0" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/Twa9Jmuokz0/ http://blog.voipspear.com/?p=27 VoIP Spear has only been live for a few weeks, yet we're seeing good numbers of users signing up for service.  It's nice to see the fruits of our labours. One nice thing about going live is that we're finally seeing how real people use VoIP Spear.  A few problems have ...<img src="http://feeds.feedburner.com/~r/VoipSpear/~4/NvqX5k4UnhI" height="1" width="1"/> http://feedproxy.google.com/~r/VoipSpear/~3/NvqX5k4UnhI/ http://blog.voipspear.com/?p=22
