In comparison, residential VoIP services have a maximum of three VoIP channels. This way any large business can make more than a a hundred calls at the same time easily. The amount of phone calls that one telephone number can take is largely limited by the available bandwidth. But a VoIP phone line can manage several calls simultaneously, which are called ‘channels’. Traditionally, it used to be that one phone number and one phone line were the same. However, the technical functionalities of the service are not always the same as legacy phone systems. Various business VoIP service providers have tiers of pricing which is similar to phone and PBX systems they want to replace.
