The following new features were added in the 9.0.0 release:

Release 9.0.009.02

SIP Endpoint SDK now supports UNENCRYPTED_SRTCP parameter per RFC 4568, and also understands "best-effort SRTP" (optional SRTP offer) per RFC 5939, accepting or rejecting SRTP based on the configured security policy.
Audio statistics provided by SIP Endpoint SDK are enhanced with additional audio decoding stats, including the number of frames decoded normally, affected by Packet Loss Concealment (PLC) or Comfort Noise Generator (CNG), or with complete silence. In addition, Voice Quality alarm is raised when no RTP packets are received for a long period.

Release 9.0.008.04

SIP Endpoint SDK now provides an API for getting SIP messages, SDP content, and negotiated codec name for the currently active session.
SIP Endpoint SDK now provides access to incoming and outgoing audio streams for the host application.

Release 9.0.006.10

Resilience to network events, such as IP address changes caused by PC Sleep/Wake, has been further enhanced, to ignore the configured reg_interval value when re-registering the DN with a new IP address.
Improved detection and handling of cases when an existing device is removed/unplugged and/or a new device is added/plugged-in.
The following options have been added to SIP Endpoint SDK:
- Updated the audio_in_device, audio_out_device, capture_device, ringer_device, and headset_name options to support regex matching for device selection.
- New options, audio and video to specify codec priorities.
For improved security, the local IP address is no longer included in the Call-ID header of SIP messages sent by the SIP Endpoint.

Release 9.0.005.06

SIP Endpoint SDK now calculates MOS during the call duration to estimate current voice quality, and can generate an alarm when the MOS falls below the configured threshold, which notifies the user about this condition.
SIP Endpoint SDK now supports additional optimization for the Opus codec.

Release 9.0.004.07

SIP Endpoint SDK for .NET no longer requires Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package.
A new log filter was added to hide DTMF data from logs.
Outgoing calls now support ringback tones.

Release 9.0.003.05

Resilience to network events, such as IP address changes caused by PC Sleep/Wake, VPN Connect/Disconnect and so on, has been enhanced.
SIP message headers now include the MAC address of the host.
TCP port ranges can be specified for client-originated connections.

Release 9.0.002.02

SIP Endpoint SDK now supports DNS SRV resolution for the URI specified in the server parameter of the Connectivity tag. You do not need additional configuration to enable this feature, but as described in RFC 3263, you should not include the port number in the server URI.

Release 9.0.001.05

SIP Endpoint SDK for .NET now uses the PJNATH library for improved ICE, STUN, and TURN support.
Updated settings for the security Section. These settings now match the naming convention of the Genesys Security Guide. For backwards compatibility, the SDK also accepts previous setting names. Note that the SDK no longer uses the tls_enabled setting.
