ZYTRAX specializes in IP Network solutions - including VoIP, Wireless LAN technology, Bandwidth Management and QoS (Quality of Service). If it's complicated and hard and has a strong communications or networking component then we're interested, have probably done it before, and can probably help you. Recent and current projects include SS7, SIGTRAN, VoIP (RTP Stack and SIP), Embedded Web Configuration, ISDN for E911, Selective Routers for E911 and the FCC Phase II mandate, and OpenLDAP enhancement. You can contact us in a variety of ways if you think we can help or provide advice.
ZYTRAX Training focuses on Knowledge Acquisition and Transfer. We provide high quality courses in DNS, LDAP and Telecommunications where our subject-matter experts are unique in their fields. We've even written books on this stuff. We don't simply teach courses, which is what most of our competition does, we transfer the knowledge of our subject-matter experts to our students. Our experts are passionate about their subjects. And yes, it is possible for (relatively) normal human beings to get passionate about DNS, or LDAP or even SS7. There is a big difference being taught by someone who feels strongly about their subject. At the end of a course our students don't just know the material, they understand it. Your organization wins all round. We provide a range of standard public and on-site courses and can customize material to meet your needs. In late 2017 we will be offering all our standard courses as a series of modular, self-paced, cost effective videos. Preview of video training.
The ZYTRAX Tech Stuff section is a collection of technical information that we have found useful over the years and which is provided as a free service to the community.
ZYTRAX has been an advocate of Open Source solutions for many years, the Open Pages is a collection of material which may help others to understand its applicability in various sectors. We have added a second in our series of whimsically named Rocket Scientist Guides LDAP for Rocket Scientists. The first in the series, DNS for Rocket Scientists, has already proven immensely popular and is being hit over 200,000 times per month and still growing strongly.
You may find some of these things interesting..or then again you may not...
To improve our service we are now hosted by super.net.sg. They provide a great service and are into all kinds of neat VOIP stuff. Thanks.

Open Source - it's complicated
Great software. Legal and free. OpenOffice has moved to the Apache foundation where they are figuring out how to move it forward. In the meantime we, like many others, have moved to LibreOffice. But it's all so serious now. We remember when Ethereal's (now wireshark) marketing slogan was "Sniffing the glue that holds the Internet together". Now that was fun. But fun is soooo last century.
There was a time when we got excited about HTML and CSS standards. Validated everything that moved. Religiously. But the world was young then and we believed what the W3C told us. HTML 5 is a joke. Whatever someone thinks it is today, or yesterday, or last week. Meh.
