The move from traditional public switch telephony network to VoIP services has been growing quite fast. All sectors of the industry are making this shift, thereby pointing out the growing reliability on VoIP telephony. There are numerous reasons for this change which has come over a period of time. Initially, VoIP termination service wasn't accepted too well by the industry. Also, broadband Internet was not easily available and lacked speed, thereby providing low voice quality. However, with the passing of time, a number of improvements have been brought about in order to make VoIP achieve the status of the new leader of the telecom industry. Voice over IP telephony has made life much easier and also increased the efficiency of the businesses through its various features.
VoIP is cost-effective, provides the same voice quality as PSTN, and offers greater flexibility and mobility to corporates, thereby unifying their communication structure. Besides this, several other features can be availed through VoIP services. They are provided by some established service providers, namely: customised VoIP billing solution for wholesale VoIP carriers and resellers, specialized business VoIP solutions for corporates, ISP's and contact centers etc. VoIP can be utilised by almost everyone to their advantage due to its high flexibility.
VoIP Service providers offer their services to wholesalers and VoIP resellers. Calculation of tariff of every individual client for wholesalers and resellers would have been a difficult task had it not been for customised CDR through real time billing. CDR or call duration report provides one of the biggest advantages to the wholesalers and resellers, by giving them the exact amount of tariff to be charged from every customer. It covers essential features like the duration of every call, and tariff to be charged after adding the profit margin of the wholesaler or reseller. It creates a separate account for every client, thereby providing ease of operations. It also helps put a call limit, which would enable a client to make calls only for a particular limit that has already been pre-set by the wholesaler or reseller.
