VoIP code supports handset protocols
VoIP products are following a trend familiar in electronics: Everything is getting connected to the Net, getting smarter, going mobile and moving toward mass consumer markets.
In a sign of the times, software developer D2 Technologies Inc. has upgraded vPort, its VoIP software for OEMs, to support multiple service protocols and classes of systems, including cellular and cordless phones. Version 1.3 of vPort, which runs on ARM and MIPS architectures, has also been ported to three additional VoIP processors.
"VoIP is maturing, adding new device types, and it's going mobile. This is enabling new user scenarios," said Doug Makishima, D2's VP of marketing.
The vPort code now comes in separate versions for gateways, desktop phones, cellular handsets and cordless phones. "Previously, we had to customize a single product for every OEM system," Makishima said.
In tandem with the release, D2 announced that China's E28 Ltd is using its software in a dual-mode cellular/Wi-Fi handset. The code runs on an ARM9 applications processor that's part of the handset's Texas Instruments Omap chipset.
The offering supports separate, proprietary VoIM protocols for services such as Google Talk, Gizmo, MSN Messenger and Yahoo's IM system. The company claims it can complete a full-duplex G.729AB call for about 90MHz maximum on a typical ARM or MIPS processor.
The vPort software requires less than 800Kbytes of flash and less than 1.5Mbytes of DRAM in the VxWorks environment.Source: EE-Times
