Are we there yet? Telecom Services' slow migration to IP. Alan Quayle
About Event

"Are we there yet? Telecom Services' slow migration to IP." - Most of the marketing noise is utter bs - Basic landscape and sizing - CPaaS history, current status, and what matters - UCaaS history, current status, and what matters - Its all about the services - solving the core business communications problem (business phone systems), and locking that service in through solving specific business problems (programmability).

Using PJSIP to Connect to Simwood Jared Smith
About Event

Asterisk has moved on from its traditional chan_sip channel driver, and is embracing PJSIP instead. Some Asterisk administrators have not yet learned to configure PJSIP. This talk aims to clarify the PJSIP configuration, especially as it relates to communicating to an Internet Telephony Service Provider, such as Simwood. I'll discuss the various PJSIP configuration objects, what they do, and how they relate to one another. With this knowledge, you should be well prepared to configure a modern Asterisk system for your VoIP provider.

Attend this highly interactive session to get key tips and golden take-aways on how to be a Geek that Speaks (and sells) fantastically well!"

Peanut butter + chocolate: using drachtio and Simwood trunks to build your own dialogflow phone gateway Dave Horton
About Event

"The convergence of call centres, AI and voicebots is a phenomenon that is radically changing and streamlining workflows today. Google's dialogflow is probably the best-known platform for building these kinds of conversational experiences, but its telephony integration offerings can be limiting and restrictive, depending on your needs. In this talk we show how to build a dialogflow phone gateway using only open source software - drachtio and freeswitch -- and then implement transfer-to-agent features that leverage the power of Simwood trunks. The solution gives you a level of control over the telephony call control and user experience that is not possible with the "out of the box" dialogflow telephony integration options, and we'll show how to implement various advanced features such as mixing speech and dtmf collection, customizing inactivity prompts for voice (which has quite different needs from chatbots), etc. This is a hands on talk, where we will explore in detail how to build a real-world application in drachtio."

SimCon 2019 Awards

The SimCon Award Winners for 2019 were presented by Rachel Riley during the evening of 7th February.

The winners were;

  • for ‘Awesome Execution’
  • CircleLoop for being the ’Kick-ass New Entrant’
  • Dan Jenkins for being the ‘Pride of Britain’
  • Fred Posner for being a genuine ‘Pre-Posthumous Legend’
  • Drachtio for the ‘Most Exciting New Open Source Project’
  • Kamailio for ‘Open Source Excellence’
  • Sangoma for becoming ‘Open Source Guardians’ were recognised for ‘Awesome Execution’; in how they very impressively executed their launch plan and achieved their objectives, given the size of their team. An exemplary demonstration of how ‘it should be done.’

In contrast, CircleLoop received the ’Kick-ass New Entrant’ award for similar success, but achieved very differently. Operating in stealth mode for some time, CircleLoop suddenly seemed to explode onto the scene, achieving commercial success with astonishing speed.

Dan Jenkins was appropriately awarded the ‘Pride of Britain’ for conceiving and delivering the highly successful CommCon Conference. He also did so with a quintessentially British flavour, creating a memorable experience, particularly for those from abroad - and made us all proud to be British!

Fred Posner was acclaimed as a genuine ‘Pre-Posthumous Legend’, a selfless, long standing contributor and supporter of the open-source community who has never sought the limelight. “We all love Fred. He really epitomises what these awards are all about”, commented Simon Woodhead.

Kamailio were awarded ‘Open Source Excellence’, a key reason being the superb management of the project. Kamailio is used within huge networks and really is the secret weapon of many modern telcos. It is open source and, in the judges’ opinion, one of the best run projects around.

Drachtio deservedly was selected as the ‘Most Exciting New Open Source Project’. Offering a completely new way architecture and being far more developer-friendly, Drachtio opens up huge possibilities for the rapid development of amazing services.

Sangoma were rightly recognised as ‘Open Source Guardians’ for their continued commitment and investment in safeguarding the open source community. Firstly by keeping both Asterisk’s and FreePBX’s development in open source and maintaining engagement with developers, but now also for their strategic commitment to Digium products, customers and partners around the globe.

SimCon is an annual event at Simwood’s HQ in Bristol, bringing the best speakers from around the community as well as covering in depth topics of relevance to Simwood’s customers.
