5 Source: norwichartcentre.co.uk Asterisk in Africa
6 Asterisk in Africa Traditional Comms Solutuions very costly Higher barrier to entry than in some economies A Strong Desire to deliver greatness Great sense of Community Asterisk takes off in the early 2000s And here we are nearly 20 years later!!!
7 Tell me and I ll forget; Show me and I may remember; Involve me and I ll understand! Chinese Proverb
8 to share To Communicate is
9 Old Model Want more, pay more E.g. $$$$ for Voic boxes Closed technology Us and them Difficult to get into Dictatorship
10 New Model Want more, work more E.g. Configure more Voic boxed Open technology, Open Source There is only an Us Easy to get into Democratisation
11 Original Asterisk Sharer Mark Spencer creates Asterisk in 1999 Started a Linux Support business Needed a phone system Did not like the options Cost Vendor lock in Decided to create his own Made it Open Source Digium is born in 2002
12 Original Zapata Sharer Zapata Telephony project Jim Dude Dixon c.2000 Saw that the advanced in general purpose CPUs meant that they would be able to do things previously done only by expensive DSPs Created Open Source Telephony Hardware Used with Asterisk Sadly, Dude passed away in early 2017
13 Zapata Tormenta Card
14 What is Community? People have a longing for belonging Support Encouragement Accountability
15 In a friendly way Accountability
16 Encouragement Gatherings, mixing with real people!
17 Support More than just technical support Although technical support is necessary
18 Version 1999 Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk Asterisk 15 Asterisk History Time
19 Recap: Asterisk 13 Current LTS, Building on Asterisk 12 which introduced New SIP stack PJSIP New API the ARI, or Asterisk RESTful Interface New BRIDGING model
20 Asterisk 14 DNS Overhaul Publish Extension States to a SIP subscription server Playback of media from a remote HTTP server via a URI Enhanced ARI media manipulation ARI Channel creation more sophisticated wiki.asterisk.org
21 Asterisk 14: Why Publish? Remove state from Asterisk Improved scalability Allows offloading of individual subscription management Separating concerns
22 Supported Body Types application/dialog-info+xml application/pidf+xml application/xpidf+xml
23 pjsip.conf [test-esc] type=outboundpublish server_uri=sip: from_u ri=sip: @exten=^1000
24 Autohint support [users] autohints=yes equivalent to: exten => alice,hint,pjsip/alice
25 What can I connect with? OpenSIPS Asterisk Kamailio Or anything else that can act as a SIP presence aggregator
26 Asterisk 15 Largely work that lays the foundations for future developments Some visible additions WebRTC enhancements Stream interface Bundled pjproject SFU (Selective Forwarding Unit) facility - VIDEO
27 Asterisk 15 Video! Asterisk 15 does video better than any prior version of Asterisk: - Multi stream enhancements to the core of Asterisk - the old single-video/single-audio stream per call limitation is broken. - Asterisk core allows renegotiation of number of video streams and audio streams as well as their attributes on demand. - app_confbridge now has support to be a generic SFU (selective forwarding unit) - All video streams go to all participants
28 SFU Selective Forwarding Unit
29 Asterisk Keeping up with changes in technology Keeping up with changes in behaviour
30 The Asterisk Wiki An excellent resource. Full of useful information and tutorials, etc. Some examples: wiki.asterisk.org/wiki/display/ast/new+in+13 wiki.asterisk.org/wiki/display/ast/new+in+14 wiki.asterisk.org/wiki/display/ast/new+in+15
31 Is Asterisk Suitable for Business Critical Large Scale Applications?
32 Asterisk MythBusters! Myths to bust Asterisk is a software PBX Open Source Software is for hobbyists Asterisk is not mainstream Asterisk has no official support Asterisk will not scale for high call volumes Asterisk is no good for high availability solutions
33 Myth: Asterisk will not scale for high call volumes What are high call volumes? Asterisk can be used as a building block with other technology SIP proxy But, just give an idea of the capabilities Asterisk on a single server handled... More than 11,500 calls! Source: Olle Johansson
34 Myth: Asterisk is no good for high availability solutions Asterisk is software... You can build high availability in any way you want! SIP Proxy Media Servers
35 Large Scale Asterisk SIP
36 Large Scale Asterisk ISDN
37 Notable Deployments Asterisk chosen by the City of Amsterdam 23,000 end points Asterisk deployed in US university > 10,000+ users Asterisk deployed by a KL-based company 130,000 users, up to 10,000 concurrent calls Asterisk-based systems handling millions of calls every week in the Philippines
38 Asterisk Myths Asterisk is a software PBX Open Source Software is for hobbyists Asterisk is not mainstream Asterisk has no official support Asterisk will not scale for high call volumes Asterisk is no good for high availability solutions
39 Asterisk fosters GROWTH! The next generation of RT Communications Asterisk as a dynamic media server Scalable, resilient systems Partnering Projects Kamailio Homer Docker
40 Digium Phones The only phones designed specifically with Asterisk in mind Standard SIP, but with extra goodies when used with a properly configured Asterisk Buy Digium to help the Asterisk project
