Android and SIP

September 25, 2008

So Android's here at last and the first thing that I wanted to know was - Are there any SIP clients already available?  I've got one listed below to check out but I'd just like to point out that although the iPhone is simply the 'coolest' phone around at the moment, I think that Android is going to be it's biggest challenge due to it's complete open-ness... There are soooo many programmers out there wanting the opportunity to write apps for Android it's going to be interesting to see if the Geeks can topple the Cool guys...

Sightspeed on Linux

September 18, 2008

You'll see from my blogs that we are fans of the SIP based Video conferencing / Chat program Sightspeed and were really pleased to see the relationship between Sightspeed and Dell is flourishing with their 'Sightspeed powered' Dell Video Chat program now being made available on Linux.   This is great news for the world of SIP as now people can delete their Skype program and have Video conversations with 4 people at the same time instead of 2 with Skype...

Go check out the Sightspeed press room here and we like this blog here from a Linux enthusiast

SIP Flanker

September 5, 2008

As you may already know, a lot of SIP phones needs to be programmed via a web interface and web interfaces usually use port 80.  Well this tool 'SIP Flanker' found here can search a range of IP addresses to see if port 5060 is present i.e. a SIP device, then probe port 80 to gain access to the web service on the SIP device.  Obviously this is a neat trick but maybe you want to try it out to see what damage can be caused.
