Deploying an alternative network to support VoIP

Should an IP audit reveal that a business’s existing network cannot support an IP telephone system and voice traffic (VoIP), the alternative would be to deploy a separate dedicated voice network.

This can be achieved with an entirely separate physical network or by using virtual local area network (VLAN) technology to separate the voice and data networks.

Another reason for separating networks is security. VoIP is vulnerable to the same attacks, intrusions and security threats as data networks; if a business has VoIP and data traffic combined on the same network, an attack on one can bring down the other.

Some businesses may also be more suited to separate networks due to industry or government mandates that determine how secure data has to be on a business’s network.

It is highly inconvenient when email is inaccessible due to network failure, but if both email and telephone communication is unavailable, businesses can suffer huge interruptions and a potential loss of income.

Bandwidth considerations may also lead to separating the voice and data networks. If a company’s existing network does not have the bandwidth to support VoIP, installing a separate network for VoIP is a solution.

swcomms recommends the deployment of VLANs to separate VoIP and data as best practice for securing VoIP networks. For more on advice in this, please do not hesitate to contact us.

Former newspaper journalist, Caroline joined the company in 2008 with no previous knowledge of the industry.

She set about stripping back all the jargon to produce plain English marketing collateral to support the sales teams. Now slightly more well-versed in the dark arts of voice, connectivity and data services, Caroline writes blogs, case studies, data sheets and social media updates to engage with potential and existing customers.

This industry is far cry from her previous working life when she worked as communications manager for Exeter Chiefs and Northampton Saints.
