Nokia’s latest Wi-Fi Internet tablet (an upgrade to Nokia 770) will support Google Talk for voice communications exclusively between other Nokia tablet users and PCs with an activated Google Talk account. Users will be able to talk directly into the device or use a headeset. Google Talk is already available on Research in Motion’s Blackberry device.

Nokia plans to support multiple voice offerings, with Skype support expected in the near future. The new Internet tablet will cost around $385.

NetLogic has introduced NLS1000HDK, a Layer 7 content processing reference platform that operates through a HyperTransport link connecting NetLogic’s NETL7 processor to AMD’s Opteron processor. The combined processors perform deep packet content inspection and complex signature recognition at 10 Gbps.

The NETL7 processor is capable of supporting more than 16 million simultaneous sessions and performing content inspection across packet boundaries. It can execute both string based recognition and Perl Compatible Regular Expression (CPRE) processing. The processor can concurrently support several hundreds of thousands of complex signatures such as virus, intrusion and application signatures, as well as thousands of signature groups.

The reference platform includes device drivers and a high-speed signature compiler compatible with both open source and proprietary signature databases.

Clear Com has introduced Voice, a 1 RU 4-way VoIP interface frame that extends intercom facilities to remote sites on a digital matrix system by connecting remote users over IP LANs, WANs, or the Internet.

Each frame comes with a PC web client application that provides IP line and audio CODEC setup as well as diagnostics that can be monitored from a centralized position. The technology uses CODECs in user selectable formats from 3.5KHz to 16KHz.

Voice features echo cancellation, an IP processing engine with RTP and ToS, and LAN bridging via a second Ethernet interface for installation or for saving local audio on flash memory.

When operating back to back, the frames can be used for up to 4 channels of: remote PC based virtual intercom stations to matrix ports or for intelligent trunk lines between remote matrix systems, or 4-wire audio pairs and 4 asynchronous RS-4422 data links between remote sites.

Iperia has introduced IperiaVX, an application server that supports voice messaging, auto attendant, conferencing, fax messaging and unified communications via Microsoft Outlook, Lotus Notes or any other message and calendar application. The server enables enterprises to integrate their unified communications functionality tightly with their SOA and portal development.

The server allows for users to send text messages to voicemail boxes, receive faxes in email boxes and store voice messages and faxes in Outlook.

The server is a Linux development platform based on JSR 168 and 180.

Convedia has introduced two new media servers including the CMS 9000 for large IMS network deployments and the CMS 3000 for enterprise and smaller IMS network deployments.

Both new servers employ eXMP, a new Linux based technology that provides cross platform media processing that dynamically maximizes processing capacity across available CPU and DSP hardware resources. eXMP also improves security and management features.

The CMS 9000 supports up to 24,000 full duplex media processing ports.

Both servers provide control interfaces for SIP, VoiceXML 2.0, Netann, MSML IETF draft, MGCP, PacketCable NCS, and H.248.

The servers feature enhanced service building blocks for tones and announcements; DTMF; conferencing (supports up to 8,000 3-way conferences and up to 12,000 participants per conference on the CMS 9000 and supports up to 200 3-way conferences and up to 600 participants per conference on the CMS 3000); recording and playback; CALEA support; video; fax; and speech.

Media support features include voice activity detection, silence suppression, and comfort noise generation. QoS is achieved via DiffServ/ToS marking and adaptive or static jitter buffering. The audio CODECs used include G.711, G.723.1A, G.726, G.729AB, AMR, and EVRC,. Video is supported through H.263.

The servers provides storage for various media including announcements, recordings, ringback tones, and other multimedia content. Internal storage is available up to 190 hours on the CMS 9000 and up to 80 hours on the CMS 3000. External storage for either of the servers is unlimited via NFS/HTTP.

Redundancy for the CMS 3000 is provided through redundant network interfaces, redundant power inputs and cooling fans and redundant BITS interfaces. For the CMS 9000, redundancy is supported via hot swappable cards and fans; redundant power inputs, blackplane, and cooling fans; redundant network I/O and BITS interfaces; 1+1 redundancy on control cards; N+1 redundancy on media cards; and in-service, hitless software upgrades.

Media server management is based on a Linux RTOS. Full management, configuration and provisioning is supported via SNMP v2c, or web based element mangement tools.

The CMS 9000 is available in a 13RU high shelf and the CMS 3000 is offered in a 1RU shelf.
