Explain two advantages and two disadvantages of VOIP.

The advantages of VOIP are as follows: 

(i) This technology leads to greater financial savings. This happens because there exists only one network carrying the voice and data provided by only one supplier. Computer and VOIP can be used simultaneously. VOIP services can also be used while travelling and can be used via internet connection. 

(ii) VOIP is becoming preferred communications options for consumers due to lower fees for basic broadband services. 

The disadvantages of VOIP are as follows: 

(i)  Security is a main concern with VoIP, as it is with other Internet technologies. The most prominent security issues over VoIP are identity and service theft, viruses and malware, denial of service, spamming, call tampering and phishing attacks.

(ii) Reliability :
Because VOIP relies on an Internet connection, your VOIP service will be affected by the quality and reliability of your broadband Internet service and sometimes by the limitations of your PC.
