Consultancy | Audit | Voice Audit

Access to lower costs & simple options

We’re qualified to audit, advise and implement improvements to voice and mobile infrastuctures with a view to reducing costs and removing unnecessary complexity. We’ll approach current suppliers on your behalf, obtain and review the billing and service agreements and complete an audit to identify and document your current voice infrastructure.

The key areas of an initial audit include:

  • Identify all voice and mobile communication circuits and the associated equipment.
  • Identify all contractual and financial details in the current provision of the voice and mobile network.
  • Identify configuration details for all audited voice and mobile systems.
  • Review third party service providers who provide equipment, circuits and support for the current voice and mobile network.
  • Identify and confirm all legacy data equipment, circuits and costs.
  • Identify the best way to remove or integrate legacy voice equipment and circuits into the new voice communications infrastructure.
  • Identify potential cost savings.
  • Identify opportunities to improve efficiency.
  • Produce an action plan to optimise telecommunications infrastructure and legacy equipment and to achieve significant cost savings.
  • Identify ways to improve resilience and reliability of the voice and legacy data facilities.

Physical audit of lines and equipment

We’ll carry out a full audit at each UK site to accurately determine the current hardware configuration and identify every circuit.

Contractual audit

All services should be covered by a comprehensive and current contract. We’ll review the current contractual protection so gaps can be identified. Every gap identified is an additional risk to the smooth running of your business in view of the risk of interruptions to service.

Perform billing audit

We’ll carry out a full internal audit of at least one year’s call and line rental charges to identify potential cost savings from billing errors.

Remove direct exchange lines (DELs)

DELs should be consolidated where possible and replaced by private branch exchange (PBX) extensions, introducing direct dial in (DDI) and increased trunk capacity where appropriate.

Consolidate maintenance contracts

Better value for money can be achieved by consolidating individual site maintenance contracts into one large maintenance contract. We’ll guide you through the process for maximum cost savings.

Mobile phone contracts

We’ll review your mobile contracts for best prices in the current competitive market. We’ll also suggest mobile technologies for improved network efficiencies and further cost savings.

Review telecoms suppliers

We’ll review alternative maintenance providers as it’s often possible to make significant savings on current contracts. In the longer term, businesses should formulate and issue a tender – request for proposal (RFP) for all their telecommunications services and we’ll help you put this together.

Process for documentation

All businesses should have a standard process for network documentation and diagrams. We’ll help you implement this and begin or update your local and centrally held libraries with documents readily available over an intranet or remote management software.

Consolidate telecommunications billing

We recommend the introduction of billing consolidation to reduce invoice processing and we’ll be happy to show you how this works and the benefits.

Incorrect billing

Incorrect charging and over charging is commonplace within the telecommunications market so it’s important for all carrier bills to be checked and verified. We’ll help set up a process to perform and manage these checks.

Group telecommunications strategy

Here at ISN we’ve helped many clients develop a telecommunications strategy for their business which provides a consistent approach for purchasing systems, security standards, documentation and use of these systems, declaring medium and long term goals for service and quality and the introduction of technology such as carrier pre-select and voice over IP (VOIP). In the short term, operational configurations need to be maintained consistently between sites. Call barring tables, extension configurations, directory management, access control and related security measures need to be reviewed or introduced where appropriate.


Call or email us for a friendly, no obligation conversation

kfpISN managed our offices and data centre relocations brilliantly, making the transition very smooth. They were always on site, ready with support and provided clear, useful handover documents. We’ve since engaged them to provide a fully managed service for our UK networks, firewalls and remote server access. We find ISN highly proactive and their service and response times are just as good whether it’s midday or midnight.
