Voip Architecture

Businesses maintained two distinct network infrastructures. These were controlled by two distinct departments as well. The installation and maintenance of these two networks contributes separately to the expenditure incurred by a business. These two networks are:

A circuit switched infrastructure for voice transmissions. This consisted of a PBX-Private branch exchange connected to the Public Switched Telephone Network (PSTN).
A packet switched network infrastructure for data transmissions. This was either a Local area network or a Wide area network. This had a gateway to manage the connections and routers to direct the data in the network.

With Voip a converged data and voice network is available. It is a good idea to look at architecture basic VoIP, to deliver cost effective solutions for your business or enterprise. Architecture is a high level design which addresses business requirements. The products and services offered are not equal in all VoIP architectures. Numerous issues need to be discussed before deployment of VoIP technologies.

Yet for all companies go about a haphazard way of introducing VoIP solutions architecture. They deploy IP/PBX’s or integrated Communications Platforms or Unified Messaging or even other toll bypass gateways. These expenditures are most often made without a proper analysis of costs and benefits.

Issues

Organizational, technical and other issues to be addressed for a voip solutions architecture are

Will the VoIP project give a positive return on investment
Will VoIP replace all the PBX’s that are for the circuit switched network
What are the added benefits in case of total replacement
Will the organization be able to tolerate an environment of loss in quality when compared to traditional PBX’s
Mission critical parts like health and safety operations, Executive staff communication and call center applications and the affect on them needs to be reviewed.
In case the business already has a LAN or a WAN network Can it be enabled to provide VoIP quality service without major impact on its existing infrastructure
Are the resources shared? (unified messaging, attendant operators and PSTN trunks)
What it the user interface(legacy analog/digital phones, IP phones or soft phones)
Management of VoIP systems in tandem with the traditional telephone systems.
IP PBX’s are more reliable because of their distributed architecture. It is easily scalable with the growing needs of the organization.
Unified communications with the ability to send messages, video or email along with the audio is another possibility of VoIP and requires larger bandwidth
Ease of use is another factor as most employees need not require training to use it
IP PBS can easily be managed with online logs for calls and thus its usage can easily be identified.
