HDVoice In Service Of Online Radio: Part 1

This morning I received a very interesting question from a reader:

I am looking for an IP phone that supports G.722 and has audio inputs / outputs so I can connect it to my mixer. We are trying to connect two studios together for an online radio station. I have yet to find anything other than high end Polycom gear that has something like RCA in/out jacks. Have you by any chance come across anything?

While not usually of concern to a small office or home office such issues are routine in broadcasting, which remains how I earn my living. Further, if you’ve read much around here you’ve probably realized that lousy audio quality on radio call-in shows is one of my pet peeves. Even online radio operators should be concerned about audio quality.

Finally, this is a novel application for HDVoice. It’s not something that I’ve done previously, so it caught my interest.

SkypeKit In The Wild

It appears that SkypeKit is now truly available in the wild. It’s been released for Linux, OSX and Windows. These last two being released just this week. Given a little time we should start seeing Skype-enabled devices and software starting to turn up.

One….in this case me…wonders a lot about where we will see the impact of SkypeKit? Will it be seen as an opportunity by the likes of Gigaset?

D.I.Y. Asterisk Appliances: A Question Of Scale

Selecting hardware appropriate for a particular Asterisk installation has been a topic of discussion ever since the emergence of Asterisk. This typically centers around choosing hardware to handle n users or x concurrent calls. Often the focus is on how to scale up to the greatest number of users for a given server. However, there can be different but related considerations as we consider ever smaller applications.

In various circles I’ve lately witnessed a minor spike in interest in small form factor Asterisk systems. I have found it curious to survey the various hardware platforms that people are considering when creating their own DIY Asterisk Appliances. To establish some perspective on this I recently posted my own history of using Asterisk my own little Asterisk retrospective.

There are quite a range of small computing platforms available to the enthusiast seeking to tinker with Asterisk. It seemed to me that an overview of such hardware and related resources would be helpful.


For my purposes I’ll only consider generic platforms suitable for a DIY project , not the commercially offered embedded Asterisk devices, of which there are many. These small host platforms tend to be in the $50-$300 range which makes them approachable for hobbyists, home users and some small businesses.
