How to Correctly Rollout an Enterprise VoIP Phone System

Voice over Internet protocol, or VoIP, has infiltrated the enterprise to replace the public switched telephone network. It brings with it convenience and cost savings, but also real security threats. As our own Carl Weinschenk pointed out in a post from last year, these threats include: "phreaking," wiretapping, identity theft, VoIP phishing (Vishing), denial of service (DoS) attacks, spamming, call tampering and man-in-the-middle attacks.

However, while security can be a challenge, it’s a fact of VoIP life that just requires careful planning on your part. To help, check out this excerpt, called “What Is IP Telephony Security and Why Do You Need It?” It comes from “Securing Cisco IP Telephony Networks” published by Cisco Press and offers a clear definition of telephony security, as well as current threats. It also gives you a guide to the tools available to defend yourself against those threats.

Below are other VoIP-related tools to help familiarize yourself with the technology and to put the right people in place to implement it in your organization.

Understanding Voice over Internet Protocol (VoIP): This paper discusses the advantages and disadvantages of using VoIP services, focusing primarily on security issues. VoIP offers cost-savings and added functionality, but can over-task your infrastructure without proper planning.

I am still not able to find a reliable and cheap VOIP device, I read many Nettalk reviews and many buyers complained of their bad customer support where people reported that they waited 2 hours for someone to get back to them and they disconnect if they are not able to answer your questions Reply

Securing the VoIP networks today needs more planning than securing the signaling and media channels. With more and more devices being connected it is necessary to remotely provision and configures those devices, and update software in the devices that are arranged throughout the network for communication.

Here at Voiceflex we try to do as much as we can to ensure our customers are protected from Toll fraud. We have over the last year implemented various anti-fraud and fraud alerting measures to try to stop this kind of activity from taking place and offer these services free of charge. I doubt there is any other provider out there that is doing as much as we are to protect our end users and resellers. To find out more check out our website or contact our sales team. Reply

Agreed with you Amanda, yeah VoIP is great technology, it is convenient and cost saving but at the same time it need more planning for its installation and use. On the one hand where technology is increasing, the security is decreasing on other.I am using speech path telephony services and enjoying the benefits of VoIP. Reply
