Ward Mundy over at Nerd Vittles has a great post today about SIP security. It’s entitled The Incredible PBX: Adding Remotes, Preserving Security. If you run an Asterisk based PBX you should probably read this. Now!
Ward’s advice really rings true (sorry for the telecom geek pun, it couldn’t be helped!) His “Baker’s Dozen SIP Security Checklist” makes perfect sense. That doesn’t mean that I can’t add my own two cents.
This is a trivial little thing, but it’s making me smile today. I was pondering how improve my experience using a soft phone on my desktop PC. Something that would be handy is a physical interface to adjust volume or mute the speakerphone when I need to answer a call incoming on my Polycom IP650. Y’see I usually join VUC calls from Eyebeam, but have to take business calls at the same time.
A solution was found at Think Geek where they offer the Griffin Technologies PowerMate, a USB attached rotary encoder……yes…it’s a knob…a glorious chrome knob!
In the first post in this series I described the common aspects of the the various Gigaset SIP/DECT systems being offered in North America. This post will go on to examine the entry-level handset, model A58H.
This handset was already described in depth back in my review of July 2009. That review, which has proven to be very popular, was done on a system using the most current firmware at the time. There have been several firmware releases since then, some adding significant new functionality. I’m not going to burn the cycles to go through that entire process again, but I will offer a brief summary of its features.
There can be no question that Counterpath is the leader in SIP soft phones. From the free offering in X-Lite to my favorite Eyebeam, and finally Bria they’ve long had a diverse offering and occupied a leadership position in the market.
In a move to strengthen the diversity of their range today Counterpath announced the launch of Bria 3.0 for Linux. This gives them a native release on Windows, Mac & Linux, which is a considerable achievement.
I can hear you now. “What! Why would Graves be recommending a plain vanilla USB memory stick? Not especially cheap nor especially large? He must be mad!” That may well be true, but it remains comfortably beside the point.
As you may know we do like our Polycom SoundPoint desktop phones around here. In fact, the IP650 has perched upon my desktop longer than another other single device. One of it’s great conveniences is the software option called the Polycom Productivity Suite, which I purchased for all my IP650s.
This software includes the ability to record calls locally on the phone with just one or two button presses. This has been tremendously useful for podcasting, technical and normal business applications.
This addition to this series is not like those that have come previously. All of the prior companies profiled are VoIP service providers that provide a degree of connectivity to the legacy public switched telephone network (PSTN), often as paid aspect of their service.
SIP Sorcery is very different. SIP Sorcery started out known as “My SIP Switch.” It’s an open source project created by Aaron Clauson, who describes it as a “SIP service aggregator.”
