VoIP – Voice over IP


VoIP refers to the transmission of voice data over IP enabled networks, rather than the use of traditional circuits of the PSTN (Public Switched Telephone Networks).VoIP is currently associated with IP telephony, which refers to the family of protocols used to deliver the voice data – RTP/SRTP, H.323, SIP, MGCP, MEGACO/H248, SCCP(Skinny) and SIGTRAN.


VoIP Benefits


The most attractive benefit of VoIP is the cost savings, which can be substantial for large enterprises and service providers. The savings can come from a number of different sources. For example, calls made over private data networks bypass PSTN networks toll circuits, avoiding regulatory and per call charges.
