Global IP Solutions, the people behind the codec package that helped bring Skype to prominence, has recently launched a blog. Amongst their first entries they decided to weigh in with a response to my recent rant about soft phones. I…
<RANT> Let’s face it, the soft phone segment of VoIP space is stagnant. There’s been little change in literally years. I’ve spent the past six months looking for a Windows soft phone that was G.722 capable. In the course of my search I’ve tried a number of soft phones. The list is getting lengthy:
Corey Andrews over at VoIP Supply also blogged a great summary of Free SIP Soft Phones a while back.. There are a couple on this list that look promising. I’m about to try both MizuPhone and Mirial.
Giving the online retailers a day to get their shops updated it seems like the new Polycom SoundPoint IP450 is going to start out selling for around $220. Given that the IP550 is listed in places for only a little…
It looks like our friends at Polycom have released a new phone, the SoundPoint IP450. This new model offers three line appearances and a new high-resolution, backlit gray-scale LCD. It also offers both wideband voice and the availability of the…
As expected the VUC call on Nov 7 about wideband VoIP proved very interesting. It was well attended with a dozen participants on the ZipDX wideband bridge and another twenty on the Talkshoe narrowband conference bridge. Our guest, David Frankel of ZipDX, did a good job of introducing wideband telephony, it’s advantages and some of the issues surrounding its implementation.
We recorded the call in several places so that we have both wideband and narrowband recordings available for comparison after the fact. History has shown that many people download the conference recordings, even many months after the original conference date. It’s evidence of “the long tail” phenomenon that we hear about so often.
However, some people are very visual so I thought I’d bolster the archive recordings by doing some simple visual analysis of the spectral energy distribution in each type of call. Happily, Cool Edit Pro (now Adobe Audition) makes it really simple to generate both waveform and spectral views of an audio clip.
Talk about perfect timing! Cory Andrews over at VoIP Supply just post a great list of 20 open source soft phones. Nice work Cory!
From this list I found that the French soft phone formerly called OpenWengo has mutated into QuteCom. Best of all, it’s G.722 capable. That makes it a viable candidate for use on this Friday’s VUC call on wideband VoIP.
