VoIP vendors. The previous article is available
New products are being developed faster than ever to
take advantage of the acceptance of IP telephony by consumers and
businesses alike. VoIP hardware and software development is the fastest
growing segment of technology once again and VCs are tripping over
themselves to fund new concepts and ideas. This is one reason for the
expected success of events like
VoIP Developer as well as that of companies like
HelloSoft, a 120-person company supplying protocol stacks, DSP
software, speech coders, echo cancellers and other components so that
developers can create powerful applications with off-the-shelf components.
Here are some of the solutions provided by the
HelloVoice is a voice over packet solution
aimed at devices big and small.
HelloSIP is a SIP stack that allows the
building of various applications.
HelloRTP/TCP is a stack allowing developers to
create media sessions, transmit and receive RTP/RTCP packets while further
allowing for codec integration, jitter buffering and buffer management.
HelloSoft IP Phone for the ARM Architecture
is a software reference design for residential gateways, wired or wireless
IP phones and other VoIP-enabled devices. The highly optimized DSP VoIP
algorithm eliminates the need for a separate DSP, meaning less power
consumption, reduced cost and rapid time to market.
HelloWLAN and HelloWireless are
products that Interface with 802.11x protocols and GSM/GPRS respectively.
HelloSoft claims they were one of the first companies
to declare you don�t need a DSP in a VoIP phone. While I can�t verify this
statement, they do seem to be on the leading edge of DSP-less VoIP
solutions. As more companies scramble to develop solutions in the VoIP
space, companies like HelloSoft are positioned well to supply the tools
needed to rapidly bring products to market. They are also simultaneously
allowing for lower cost devices as well as ones that can be brought to
market more quickly. All of these issues are of crucial importance to
companies developing the next generation of VoIP solutions.
