A developer’s view

3. Asterisk SCF recap
• Scalability
• Fault tolerant
• Extensible
• Performance

4. Developer Ecosystem
• Tip of the hat to Digium Inc
• Developers involved throughout
• Requirements from ecosystem
• Open development process

5. What I wanted
• Extensibility
• Modern Language support
• Dynamic
• Cloud friendly

6. The Experiment
• Git snapshot of current code
• Not a release !
• Not a routing engine
• Help from asterisk-scf-dev IRC
• Used Groovy (via JVM)

7. Live code demo
• Code at github
• https://github.com/steely-glint/ascf-groovy-
demo

8. Auto

Static code un-demo

Connect to

Ser vice ic = Ice.Util.initialize(null);
sloc = ServiceLocatorPrxHelper.checkedCast(ic.stringToProxy("LocatorService:tcp -p 4411")); List all
services = Arrays.asList(sloc.locateAll(new SipConfigurationParams())); ser vices

Find the SIP sc = ConfigurationServicePrxHelper.checkedCast(sipconf[0]);
Session cgrps = [ Pick the first
Manager(s) { g = new SipGeneralGroup(); g.configurationItems = [:] ; return g} , one

u.name = "h-udp";
u.configurationItems = [ "host" : new SipHostItem(1,"127.0.0.1",5081)];
Define a return u},
couple of local { u = new SipUDPTransportGroup(); Convert to
u.name = "h-udp1"; ICE friendly
endpoints
u.configurationItems = [ "host" : new SipHostItem(2,"127.0.0.1",5080)]; format
return u}];
grps = cgrps.collect{item -> item.call()}
sc.setConfiguration((ConfigurationGroup[])grps.toArray()); Send the
request to
ASCF

9. What have I proved ?
• Dynamic configuration
• Cloud friendly
• JVM language support (java, scala, javascript)
• Components independently managable

10. Voice 3.0 ready
• Adornment
• Session Cookies
• webRTC
• Hooks

11. Conclusions
• Still a work in progress
• Much to be done
• Much to be documented
• Fundamentals are right
• Future-proofing is in place
