VoIP Software
Voice over Internet Protocol, or VoIP,
architecture consists of end-user devices,
gateways, gatekeepers and the IP network. The
software for VoIP is a collection of programs,
applications and protocols to manage the
architecture. The significance of VoIP software
is underlined by the increasing demand for
higher quality of service from consumers.
Effective software programming translates into
effective management of calls—in terms of
routing of the calls through the least congested
paths—and clarity of voice.
VoIP software can be classified according to
the different functionalities in the VoIP
network. These functionalities include the
management of user interfaces, call processing,
network management and billing. User interface
software handles the interface to the user of IP
telephone. The important features of the user
interface include algorithms to compress voice
data, echo cancellation and encryption.
Call processing servers are run by software
to map the destination of the call. The software
is a database program called soft switch. The
software translates the phone number into a
unique IP address after checking the validity of
the number. It connects the two devices on both
ends, after alerting the called party of the
incoming call through a ring.
Call administration software, called
consoles, are applications that manage the state
of the calls and the distribution. This software
provides bandwidth management. Some of the
standard protocols are H.323 session initiation
protocol. In order to maintain the quality of
service, real time protocol (RTP) is employed.
The software also manages the networks.
Some of the customer-oriented services
managed by software are billing services. This
includes pre- and post-paid services. Some
provide voicemail services that synthesize voice
for mails. IP soft phones are managed by
software that lets the user directly connect
with the VoIP provider through a computer. Skype
software is rapidly capturing the market with
millions of phone minutes.

Another area where software provides services
is in the call-monitoring systems for call
offices to manage the calls and Computer
telephony Integration for businesses.
Software development is accelerated by the
need to solve various issues such as loss of
packets and sequencing of packets.
