Release candidate snapshot downloads of the Sirius release (PTLib v2.8.0 & OPAL v3.8.0) are now available. This is the last step on this becoming our standard stable release, superceding the Lalande release.

Main features are:

• Support for SIMPLE and OMA variants for presence.
• MSRP instant messaging fully implemented.
• OPAL based “mixer” class for audio and video with sample MCU.
• T.38 and G.711 fax support using SpanDSP as a DLL/Plug in. Fixed numerous compatibility issues from Lalande, which was pretty broken.
• H.239 client side support.
• Call recording can now include video to AVI file (Windows only at present)
• G.722.2 (aka GSM-AMR wide band) codec plug in.
• Can now handle large numbers of SIP registrations or subscriptions.
• “Internal transfer” feature for switching a network connection (e.g. SIP) between subsystems, e.g. call starts in on an IVR and then moves to the MCU or the CP sound system.
• New simplified C++ API based on the “C” API.
• Ruby interface classes.
• The usual innumerable tweaks and fixes.
