SIP SIMPLE client SDK 0.30 release

Added by Adrian Georgescu over 12 years ago

SIP SIMPLE client SDK 0.30 release

There is a new release of SIP SIMPLE client SDK available. Version 0.30 incorporates Presence functionality based on standards from SIMPLE Working Group, compatibility with OMA, XMPP interoperability, GRUU (RFC5627), MSRP multiparty conferencing (MSRP switch) and critical bug fixes.

Presence

At over 15,000 lines of Python code, Presence is by far the most complex part of the SDK and the reason it took so long to produce. Presence functionality is now incorporated into an easy to use address book that can be used to develop contact-driven Real Time Communication clients without having to deal with the complexity of SIP signaling, XCAP storage and data replication among multiple devices.

SIP SIMPLE client Presence API is simple to use, at minimum one can use Group, Contact and Policy classes each of them with add/delete/update methods and eight notifications in total to manage the address book. Subscribing to Presence for a contact and granting access to our own presence information are boolean that can be set for each contact. Next Blink release will incorporate this functionality.

The API documentation is available at: http://sipsimpleclient.org/projects/sipsimpleclient/wiki/SipMiddlewareApi#Addressbook-API

XMPP interoperability

Interoperability with XMPP for MUC and Presence payloads allows for the SDK to be used in border applications that interact with both SIP and XMPP protocols. Next SylkServer release will incorporate this functionality.
