Hello all,
OpenSIPS 1.11 has a new addition, the "script_helper" module . The
purpose of this new module is to help you *start in an easy way with the
OpenSIPS script*. *The learning curve gets milder*as the beginners can
start with a simplified format of the script - the idea is to shift the
main focus on routing the SIP initial requests (which define the service
logic), while transparently handling a lot of "standard" SIP scripting
logic, in order to both save script coding time and mitigate potential
SIP scripting errors. This tutorial offers both a brief overview on the
features of the new module and an example script.
The current features of the module:
1) *transparent handling of SIP sequential requests*
* sequential requests are properly and silently handled - they will
not hit the script at all anymore for initial SIP requests, the module
performs record-routing (i.e. OpenSIPS adds itself in the signaling path
using a Record-Route header), after which the main route is triggered,
just as before
* for sequential SIP requests, the module is automatically doing
loose_route() for proper routing.
* optionally a special route may be run just before all sequential
requests are routed out
2) *automatic dialog support*
* automatically create dialog support for the INVITE-based sessions
* for sequential requests within a dialog, a complete dialog
matching (Call-ID, From-tag, To-tag) will be attempted if the quick
'did'-based Record-Route parameter matching fails
A nice tutorial with script examples can be found at:
http://www.opensips.org/Documentation/Tutorials-ScriptHelper-1-11
The module documentation can be found at:
http://opensips.org/html/docs/modules/1.11.x/script_helper.html
As future directions for the module, we are looking to include support for:
* auto authentication
* auto NAT traversal
* auto registration handling
Enjoy,
