Gigaset Phones & SIPGate
In a previous post I described the settings necessary to have my Gigaset A580IP register for use with OnSIP. This time around I’ll show you the settings necessary to use SIPGate in the US.
In-Stat On Media Phones
It’s no secret that I’ve been living with a couple of Polycom VVX-1500 Business Media Phones around my office for the past few months. My review of these devices will shortly run over at Small Net Builder.
This is one of the few times that 3000 words seemed like a problem. That is, I could use more space to get into more detail about the devices. Perhaps we’ll run a follow-up later on. That’d be great, presuming that I get to run a trial installation of the phones as I hope.
Anyway, Media Phones. It’s a whole new category. It’s like the iPhone for the home or office. That includes some other devices that I’ve shown interest in, like the Verizon HUB from Open Peak, and Glass from Cloud Telecomputers (pictured).
Analysts In-Stat have published a report on media phones. It’s free. Go fetch it. I’ll wait.
Ruben’s Take On The Citel C-4110 IAX/SIP Phone
There's just way too much interesting gear out there for me to try all of it. That's at least part of the reason why I was happy to read Ruben's review of the Citel C-4100 IP phone. Back in May…
Review Delayed: Dreamwave SIP-D28P
I wanted to be working on reviewing the Dreamwave SIP-D28p by now, but that effort has been delayed due to a firmware issue. The phone is powered-up and running. I’ve been able to use it a bit, exploring its firmware, web GUI, etc. It shows some promise. There are some nice features in the device.
However, I came to a screeching halt when I found that the phone doesn’t provide sidetone into the handset. This stopped me dead in my tracks. The lack of sidetone makes using any phone very unnatural. Thus I’ve not been able to put it on my desk and actually use it as my primary phone. That’s the process that forces me to gain enough experience with a device to write about it sensibly.
GIPS Comments On G.722
Not long ago Dr. Jan Linden, V.P. Of Engineering at GIPS, wrote a really good blog post called G.722 Revisited. In it he considers the trend toward the use of G.722 in the rollout of new wideband telephony projects.
Dr. Linden collected a nice stable of facts in making his points regarding the use of G.722. It’s simply old and less than optimal for use over IP networks. It’s not as bandwidth efficient as many of the new codecs, resulting is lower call quality for a given data-rate. He points to a 2007 study of ITU standard wideband codecs that is quite clear that G.722 is back-of-the-pack from a pure performance perspective.
The post is a great collection of information and he is absolutely correct in making all of his points. But I think that there may be more to it than the argument he lays out, strong though it may be.
The Gigaset A580IP, Gizmo5 & Google Voice
This is just too handy to remain hidden away in a comment so I thought I’d make it a proper post on it’s own. Gigaset Communication‘s Tony Stankus responded to a question asked in a comment on my A580IP review. The question was, how to setup the A580IP for use with Gizmo5 and Google Voice?
