It might be a while before Internet telephony with VoIP (Voice over Internet Protocol) reaches mass use, but there’s already a fast movement in that direction. A lot of organizations are not only attracted to VoIP’s promise of cost savings, but its ability to move data, images, and voice traffic over the same connection. Think of it: a single Internet phone call can take information sharing to a whole new level.
Asterisk is disrupting telephony and Customer Relationship Management(CRM)
Many IT administrators and developers are actively looking to set up VoIP-based private telephone switching systems within the enterprise. The efficiency that network users can reach with it is astounding- And cheap, if we build the system with open source software like Asterisk. There are commercial VoIP options out there, but many are expensive systems running old, complicated code on obsolete hardware. Asterisk runs on Linux and can inter-operate with almost all standards-based telephony equipment. And you can program it to your liking.
