• SS7 termination and tapping features

• Support for BRI ISDN interfaces on MediaPack™ MP-40x

• RTCP-XR (RFC-3611) real time call quality reporting

Besides these outstanding enhancements, Software Release 5.0 includes many additional features that are covered in detail in the product notice. AudioCodes Release 5.0 software is currently shipped factory installed and software upgrades are available for many previous products.

Software Release 5.2 includes additional enhancements, where the most important ones are:

• Mediant™ 1000 is enhanced with conferencing and IPmedia functionality with SIP MSCML which is important for the IP-PBX Market - Media processing Module (MPM).

• Mediant 1000 as a scalable modular platform is enhanced with a new additional interface type – module with BRI port interfaces.

• QSIG interworking with SIP Services

• Stand Alone Survivability (SAS) on the MediaPack™ family and on the Mediant 1000 implemented in the SIP control protocol.

• Sigtran Enhancements in capacity and features.

• Variety of SIP enhanced features to enhance the feature set of several application

The Mediant 1000 is enhanced with conferencing and IP-Media capabilities with SIP MSCML – Media processing Module (MPM)

For IP-PBX vendors that run their software on a Mediant 1000 hardware platform, Software Release 5.2 has a significant enhancement - conferencing and IP-Media capabilities.

The MPM module provides the DSP resources required to support enhanced applications such as conferencing, announcements, recording and transcoding.(Supports conferencing with SIP NetAnn).

The Mediant 1000 can host up to 2 MPMs, the MPM includes the DSP resources required to offload the media intensive applications from the CPU, supporting standard MSCML (Media Server Control Markup Language), it allows the application server to easily utilize the MPM resources for media processing features. Supporting the media processing features both on the TDM side and the IP side enables the OEM vendor to easily integrate into the platform key application such as voicemail / unified messaging, IVE and conferencing. The main IPmedia supported capabilities are IVR, Play from local and Play and record from HTTP.

The MPM module supports up to 20 conference users, running from 3 way conferencing and all the way to 20 simultaneous conference users. Up to 60 IP media resources are supported simultaneously in the Mediant 1000 (with 2 MPMs).

BRI Module on the Mediant 1000

Up to 5 BRI modules can be installed in a Mediant 1000, each BRI module has 4 ports of S/T interface for 8 VoIP sessions providing a maximum of 20 BRI ports on a Mediant 1000 where every port can be configured as a network side or user side. Each BRI module can be configured with PSTN Fallback capabilities for enhanced reliability.

Stand Alone Survivability (SAS) on the MediaPack family and Mediant 1000

The Stand Alone Survivability (SAS) that was introduced on the Mediant 1000 in Software Release V5.0 is a key differentiator for AudioCodes Media Gateways providing enhanced reliability and survivability for customers using AudioCodes Media Gateways in Service Provider (IP-Centrex) deployments as well as Enterprise multi branch deployments.

In Software Release V5.2 the SAS feature is supported on a wider range of products as well as the enhancement of the implementation mechanism. While the SAS feature in Software Release V5.0 was supported on the Mediant 1000, the Software Release V5.2 is supported on the MediaPack family. The implementation of the SAS feature in software release V5.2 is in the SIP control protocol running on the MGW without the requirement for the additional OSN Server on which it ran in Software Release V5.0.

Sigtran Enhancements in capacity and features:

• Increased numbers of signaling links on the Mediant™ 2000. The number of signaling links per TPM is increased from 8 to 32 links – providing enhanced flexibility in deploying the Mediant 2000 in SS7 deployments.

• New Sigtran feature – UAL support of two SCTP connections (associations) per one interface group on the Mediant 2000.

Variety of SIP enhanced features to enhance the feature set of several applications (detailed list in the product notice), for example:

• Enhancements for contact center applications: Disconnect on SIT (Special Information Tone) – important feature for predictive dialer in outbound calling center, enhances the call center productivity by releasing the channel of the agent.

• Enhancements for IMS Architecture: AKA Support added to the gateway authentication – The AKA mechanism performs user authentication and session key distribution in IMS and Universal Mobile Telecommunications systems (UMTS) networks. AKA is a challenge response based mechanism that uses symmetric cryptography, meaning that not only server authenticates the client but also the client authenticates the server.

• Enhancements for the Mediant 1000 as a platform for IP-PBX vendors: - KPML Support (RFC 4730) – Key Press Stimulus Protocol (KPML) supports out of band digit notifications according to a subset of KPML specifications (RFC 4730). An application that wants to collect information about digits entered by the user can define the list of digit patterns and the duration (for long key presses) and will receive alerts for these specific DTMFs. - Support call hold reminder ring - this feature is required to remind the FXS user hanging up a call that there is currently another call on hold, the reminder is executed by ringing the phone using a special ring and when/if the user picks up the phone, the call on hold becomes the active call. - Support join header (RFC 3911) – enables place into conference (3 way call). A framework that enables SIP user agents to logically join existing SIP dialog (e.g.2 party conversations), between two additional SIP user agents. The requesting user agent will be added to the conversation space of the existing dialog – creating a conference between the user agents.

• Enhancements for Military and defense applications:
  Support MLPP (SIP<->PRI) – Added support for multi-level precedence and pre-emption (MLPP). This feature is for IP-based applications (e.g., Softswitch), which allows users different levels of precedence and the ability to pre-empt callers with lower precedence.
