Voice over IP (VoIP) deficiencies

By: Roger Wilco
The basic premise of VoIP is simple: rather than using a dedicated telephony network, voip phone calls are carried over existing data networksThe primary motivations for doing so are cost (Roaming) and convenience as VoIP is significantly less expensive than typical telephone long distance packages, plus one high speed Internet connection can serve for multiple phone lines.Business and homeowners hearing about the cost savings of VoIP and who want to be prepared for next-generation services as they become available, but don't want to completely forget about the fax machines and phones they currently use.Since its first publication in 1999, SIP has generated a high level of interest in the VoIP industry, and many people believe that SIP will become the de facto standard protocol for future voice networks.The real problem that a malicious code for Voice over IP (VoIP) would suppose is that it opens a whole new field for hackers to create new types of malware.

By using viable IT security standards, business voip systems can be properly protected against any possible waves of attacks. Meanwhile, real security requires encryptions and cryptographic authentications. And more vulnerabilities can be expected for several reasons through this new protocol: the large number of differing vendor implementations, the complex nature of this collection of protocolsComputer Technology Articles, problems with the various implementations.Network security issues with VoIP may emerge in the near future as Voice over IP phone services continue to gain popularity.
