SIP survey results are in..!!!

May 21, 2012

At last.... the results of the SIP survey 2012 are in and now published online - you can find the document by visiting

With a rise from 400 to 500 on last years respondents and a few new questions  we aimed to take a look at SIP Trunking and specifically, to find what the most common issues during SIP Trunk deployment are and what can be done to make these issues occur less frequently, if at all.

There are some great  numbers to check out such as:
  • 55.5% or respondent companies are using SIP trunks now!
  • 70% have a VoIP PBX as their main PBX
  • Avaya leads the manufacturer list
  • Acme Packet is top of the SBC list
  • Most problems reported last year are still occurring
  • Yet support seems to be getting better from most companies
  • Also, Fax seems to be requested more than HD voice
There is a lot of interesting stuff in this document along with comments from experts in the SIP trunking 'space'.

Thanks to all for participating and of course, we'll be running this again next year.


March madness!

April 10, 2012

Phew! what a month March was – I was running around all over the place and The SIP School team rarely saw me.

First up, UCexpo in London at Olympia on the 6th.

This was a great show and apart from the fact that a cancelled train service almost made me miss my own session it was a well spent day.

My main observation from the show was that there was a big presence from Microsoft and a lot of other manufacturing/service companies wanting to show that they are working hard to enhance a ‘Lync based’ UC solution with their own offerings.  Cisco had a very small presence though it’s big rival Avaya did have a reasonably sized booth though right up the corner? 

Unified confusion - I think not!

February 20, 2012

Last year I kicked off something called ‘The SIP trunk challenge’.  The idea was to try to find a good clear description of what SIP trunking is and the challenge worked well with over 353 votes and a worthy winner – blog here.

So I got brave…  I tried again with the ‘Unified Communications challenge’ with the remit of:

“Define Unified Communications in a simple phrase that when used to explain UC to a new client, they ‘get it’ right away and then want to get their cash out.

The SIP School and OnSIP

January 10, 2012

SIP education is what we do and we like to think that we help people become confident in this ever changing protocol.  To help them learn about SIP we advise students to get themselves SIP addresses to run the labs and to help them, we point them to a myriad of free services such as SIP2SIP, Iptel, and many many more - in fact, the more the better as it gives people choice and also alternatives if one doesn't work too well in their part of the world.

Today we added another option by working with our friends at OnSIP.

When a new student joins us, they are automatically provisioned an OnSIP SIP account for the domain i.e. ...  This adds a fantastic dimension to our training service and helps our students even more.

So a BIG thanks to OnSIP and for the full press release, please read on...

The SIP Trunk Challenge - Winner!

November 14, 2011

So it all started off with the question ‘What is a SIP trunk?’

I went to the ‘Channel Partners’ conference in Chicago back in September and this question was being asked so many times it got me thinking that there is no single and clear explanation that people can use over and over again and be sure that the client understands what SIP trunks are.  Of course, a lot of clever people out there have no problems explaining what a SIP trunk is and their clients are making SIP calls all day long and reaping the benefits of this ever evolving technology but after hearing this question repeated over and over again – not just at Channel Partners but other events such as ITEXPO and Enterprise Connect I thought that people in the Telco business could help me out in my quest.

So, I placed the question on a number of groups on Linked in and received around 90 responses.

SIP and FoIP

August 1, 2011

So after a few months of hectic writing The SIP school is pleased to roll out its latest updates to the SSCA® SIP training program.  There are the usual changes due to the ever evolving nature of SIP but most notably this time around is a brand new module on SIP and Fax over IP and quite a revamp of SIP trunking, which of course is the one thing everyone talks about in the industry. 

Full update details can be found at this link 

SIP Communication training for Sales and Marketing

May 6, 2011

We've finally managed to complete the latest round of updates to our Sales and Marketing program and had to change it's name to reflect the changes.

SIP Communication services for Sales and Marketing professionals with the SSMP™ Certification test is now live and ready for people to access. 

Here's the overview and we hope you like the addition of UC and Hosted PBX to complement the SIP Trunking elements.


To effectively participate in the Unified Communications, Hosted PBX and SIP trunking boom, sales and marketing professionals need to understand the opportunities and techniques required to succeed. The SIP School™ is „the‟ place to learn all about SIP (Session Initiation Protocol) and prepare you for the marketplace.  There is so much information about SIP on the Internet that is both hard to read and poorly presented that it is difficult for people to learn about this most importantprotocol.
