OpenSIPS 2.3 - when ?
●Beta release - 16th of March
●Stable Release – 26th April 2017
●General Availability – 2nd of May 2017

7. Bogdan Iancu - OpenSIPS Project
Keyword “Integration”
●VoIP platforms/systems are more than SIP Engines/OpenSIPS
●OpenSIPS must have the ability to integrate and work
together in all possible means with other projects,
protocols, systems or concepts.
7

8. Bogdan Iancu - OpenSIPS Project
Benefits of the “Integration”
●Ability to build complex systems
○More possibilities means more value
○Brings in third-party value
●Reduces the user effort
○As required knowledge
○As required work
8

9. Bogdan Iancu - OpenSIPS Project
The Success of the “Integration”
●A collaboration with the teams of the partner projects in
terms of ideas, brainstorming, solutions and of course,
work.
●A collaboration that resulted in solutions and benefits
for all the involved communities.

10. SIPCapturing/HOMER Integration

11. Bogdan Iancu - OpenSIPS Project
Integrated capturing
●non-SIP tracing - tracing more than SIP
●data correlation - see the being picture

14. FreeSWITCH integration

15. Bogdan Iancu - OpenSIPS Project
Mid-registrar
●An OpenSIPS frontend can offload and help FreeSWITCH with
REGISTER traffic processing.
●OpenSIPS can prolong the registration sessions or can
aggregate all the registration for the same
AOR/subscriber.

FreeSWITCH driven LB
●get load feedback from FreeSWITCH via ESL
●do an accurate load-balancing over a FreeSWITCH cluster
●Adjust the load distributions to correct external
influence

20. CGRates Integration

21. Bogdan Iancu - OpenSIPS Project
CGRates
●SIP without billing is like a dinner without a good wine
●CGRateS is an open-source rating engine used for
○carrier-grade, multi-tenant, real-time billing
○Post and pre paid

22. Bogdan Iancu - OpenSIPS Project
CGRates Integration
●Call authorization
●Accounting and charging
●CDR generation

24. SIP-I Integration

SS7

$$$$$$$$$
●SS7 interconnections are costly and difficult to set

26. Bogdan Iancu - OpenSIPS Project
SIP-I
SIP-I is very powerful as:
●it is SIP based, so simple to deal with (comparing to
SS7, of course )
●it exposes SS7 specific data via the ISUP payload

●strip_body_part(“application/isup”)
●$isup_param(Called Party Number | Address signal)

29. Event Based Routing

30. Bogdan Iancu - OpenSIPS Project
Event Based Routing
Addressed problems:
●communicate and exchange data with the processing of a
different SIP message
●synchronize or wait for actions related to the
processing of a different SIP message


30

31. Bogdan Iancu - OpenSIPS Project
EBR concepts
●Implements a Subscriber - Notify model
●Events - triggered by actions / data processing during
runtime; events carry custom data.
●Subscriber - any IPS msg processing may subscribe for
events (with filtering)

EBR scenarios
●Push notification
●Call pickup
●DTMF call driving


34

35. Bogdan Iancu - OpenSIPS Project
Push Notification scenario
●we want to deliver the call right away to already
registered UACs, without any waiting due the PN logic.
●we want to do parallel forking (simultaneous ringing) to
newly registered UACs, as soon as it registers (as a
result of PN)
●we want to keep the call on, even if the registered UACs
declines it (maybe due to DND) and give a chance to the
PN to trigger the mobile device registration.

36. Bogdan Iancu - OpenSIPS Project
Push Notification
Route[do_pn]{
t_newtran();
t_wait_for_new_branches();

$avp(filter) = "aor="+$rU+"@"+$rd;
notify_on_event("E_UL_CONTACT_INSERT","$avp(filter)","fork_call");

launch ( exec("/my/pn_triggering_script.sh") );

if (lookup("location"))
t_relay();
}

route[use_new_contact] {
t_inject_branches("event");
}

37. And More….

38. Bogdan Iancu - OpenSIPS Project
RabbitMQ enhancements
●Direct trigger of RMQ messages from script
●Custom data can be pushed into RMQ messages
●Custom formatting (attributes/headers) of RMQ messages
●Fine tuning of the AMQP protocol options


38

39. Bogdan Iancu - OpenSIPS Project
XML wise variables
●provides parsing and manipulation of XML documents
●Very useful for Presence related data manipulation
$xml(body) = $rb(application/dialog-info+xml);
$var(identity) = $xml(body/dialog-info/dialog/remote/identity.val);
39

40. Bogdan Iancu - OpenSIPS Project
Extended Async Support
“Launch()” script statement
●Spinoff some processing without waiting for it to finish
●Continue the script execution (no resuming)
...
launch( avp_db_query("insert into .....") );
xlog("insert started, continuing...\n);
...
40

41. Bogdan Iancu - OpenSIPS Project
More Reliable Accounting
A more reliable way to populate ACC data
●$acc_extra[]
●$acc_leg[] (instead of old complicated AVP)
modparam("acc", "leg_fields", "log: caller; callee")
...
acc_new_leg();
$acc_leg(callee) = $ru;
...
