Much disussion has centred around the security and privacy aspects of VoIP as well as significant issues in relation to emergency calls. This article will focus on the importance of considering the wider implications of security in the context of utilsing VoIP.
Laptop Battery There are numerous security concerns with VoIP with two common ones being the privacy aspect of eavesdropping in on a conversation and a second being the hacking into and use of a VoIP users account.

Thinkpad It is arguable that focus in relation to security aspects of VoIP technology has and continues to be improved and addressed. Even if this is not the case are there bigger holes elsewhere? Most VoIP users are operating on something other than a dedicated VoIP computer, network, broadband link. That is they are using an existing computer and everything that goes with and on it as well as a broadband link utilized for general internet purposes.

Microsoft Thus the same risks and concerns in relation to security of personal computers and data transmissions therefrom is extremely relevant to the VoIP world. This is especially relevant if using software applications as a telephone rather than a standard telephone through an Analog Telephone Adaptor (ATA).
Almost 10 years later, the trend of abandoning desktop computers in favor of laptops is creating a new era in computing security.
Laptop Computers In the case of software on a home PC it would therefore be vital to secure the PC and operating system to the highest level possible by use of firewall(s) and anti virus software for starters. This should be obvious but how many users don't keep their firewall and anti virus software updated along with the operating system as new security exploitations are encountered and security upgrades supplied?

Laptop Computer Additionally consider all things wireless. Anything wireless means a radiocommunications transmitter at the departure point and a receiver at the other allowing the possibility of interception somewhere inbetween. For example users of a Wireless LAN such as one compliant with the 802.11 standard would need to consider security in relation to the wireless or radiocommunication transmission aspect.
A hardware IP phone, also referred to as a 'hard phone', is a self contained IP telephone. It looks just like a conventional phone, but instead of a conventional phone jack, it has an Ethernet port through which it communicates directly with a VoIP server, VoIP gateway or another VoIP phone. Since a broadband hard phone communicates directly with a VoIP server, VoIP gateway or another VoIP phone it does not require any personal computer nor any software running on a personal computer to make or receive VoIP phone calls. It can be used independently, all that is required is an internet connection. While PC based software solutions are cheaper, a hard phone is the best solution for IP telephony.
Desktop Computer Whilst things have come a long way from the days of non encrypted cordless phones and analog mobile phones that could be intercepted on a commercially available scanning receiver, along with Dual Tone Multi Frequency (DTMF) decoders meaning not only could conversations be listened in on but PINs, account numbers etc entered via the keypad could be decoded, you do not want to be the car with the mobile phone visible on the front seat or the house with the door or window left unlocked.
Notebooks By examining, assessing and addressing the basic security aspects in relation to PC/server setup along with increasing security for the Voice Over Internet Protocol technology, it is hoped that the analogy could be drawn that so many others are more vulnerable that you will either go unnoticed or not be targeted due to the availability of much easier and worthwhile targets.
