is a common knowledge now that 'Voice Over Internet Protocol' (VOIP) is the
next big thing since Internet. In next few years majority of households and
businesses across the world would be communicating via VOIP and they will be
using VOIP devices for their communication.
All VOIP devices like software phones, hardware IP
phones and Asterisk (www.asterisk.org) applications allow peer-to-peer
VOIP calls. This is an inbuilt feature that is already available in
VOIP devices. Peer-to-peer calls do not go through a VOIP service
provider and the calls are 'free' as in 'free beer'. In order to
make a peer-to-peer call, all that is required is the 'peer
connection information' of the other user.
Voice over IP Directory Services (voipDS)
To enable peer-to-peer calls globally, the
following setup is required
a central repository that stores peer connection information
of all users
an easy way to search and download peer
connection information from the central repository of other
Voice over IP Directory
Services (voipDS, pronounced as 'voip' D S) is a service that
precisely addresses these needs. voipDS is a central repository for
peer connection information and also provides an easy way to
search peer connection information of other users.
Any user can connect to voipDS and register
their 'peer connection information' (PCI). They can also search for
PCIs of their friends and family members. They can then download the
PCI and configure their VOIP devices to make peer-to-peer calls.
Business users can also leverage voipDS. They
can find their retailer's, supplier's and manufacturer's PCI and
establish peer-to-peer communication with them. This would
drastically reduce their communication costs.

Voice over IP Directory Service (voipDS) would
be available shortly at www.voipds.com.
voipDS can be accessed by the normal web based interface or by using
'voipDS protocol'. Web based interface is used for manual
configuration while'voipDS protocol' is used for automatic configuration of
VOIP devices. 'voipDS protocol' is a device independent protocol
that defines the communication between VOIP device and
voipDS. Using this protocol, PCI of the users can be registered with
voipDS, PCI of other users can be retrieved from voipDS and VOIP
devices can be automatically configured to make peer-to-peer calls
with the other user.
This site www.voipds.org,
provides voipDS protocol internet draft, schemas and xml samples as
defined by the protocol. A FAQ is also available to answer some of
your questions. An implementation document, that explains the voipDS
protocol implementation for majority of VOIP devices will be

of 'Open source' movement and it is released under GPL
