blackberryThe BlackBerry 7270 supports IP telephony to extend enterprise desktop phone functionality to a BlackBerry wireless handheld.

Research in Motion Limited has partnered separately with both Nortel Networks and 3Com Corporation to deliver SIP-enabled VoIP over Wi-Fi LANs to a new Blackberry handheld.

RIM and Nortel are focusing on interoperability and integration between RIM’s BlackBerry enterprise platform and Nortel’s MCS 1500 multimedia communications server, while RIM and 3Com are integrating 3Com’s IP PBX and wireless WLAN switch with RIM’s BlackBerry wireless solution for WLAN networks.

The objective in both cases is to allow seamless roaming of office-based VoIP calls within internal WiFi domains, top enahance the mobility of enterprise voice and data.

Both approaches rely on standards-based interoperability based on SIP. The Internet orientation of SIP readily allows always-on BlackBerry applications such as email, VoIP, browser, organizer, push-based services, security and back-end integration to be tied in to existing office PBX functionality.

The products are being demonstrated now, with general release expected soon.

SPIRIT Introduces Prosodic VoIP Conferencing Software

November 29, 2004

 

SPIRIT Corp introduced its new Multi-PASS embedded conferencing software designed for server-based and serverless peer-to-peer PC VoIP communication and conferencing.

SPIRIT Corp‘s Multi-PASS is a conferencing solution providing both server-based and serverless peer-to-peer and multipoint conferencing, based on SPIRIT’s Prosodic Active Speaker Selection (PASS) algorithm.

Prosody is the study of patterns of stress and intonation in language. By combining prosodic analysis with with dynamic utterance modeling, SPIRIT says it has made speaker activity estimation more accurate, enabling each speaker to get the best chance or time to speak, to be heard, and to hear all the meaningful speech of others.

The software enables any number of conferences and unlimited number of participants per conference, without degradation of speech quality and user experience, preserving clarity as in a face-to-face conversation, according to the company. The analysis is performed on each speaker’s side and does not load server CPU.

Controlled by the PASS software info, the conferencing engine optimally passes voice data from active speakers to the other participants. Broad bandwidth is not required, and due to smart traffic channeling, voice traffic and channel usage are optimized to reduce CPU load.

The company’s objective is to provide better-than-PSTN quality at low cost, thus enabling it to serve the exectutive conferencing market, as well as all other conferencing needs, all via VoIP.

SPIRIT communication software works within hardware solutions from clients including Agere, Atmel, Furuno, JRC, NEC, Nortel Networks, Panasonic, Philips, Samsung, Siemens, Tadiran, Texas Instruments, and Toshiba among 100+ other OEMs. Texas Instruments is shipping SPIRIT’s software ROM-ed into TI C54CST processor.
