ISP's are currently battling the broadband war. The race for customer aquisition is aggressive. What is the holy grail... VoIP or basic broadband revenue? The answer lies in the current broadband price offerings of ISP's.
The cost savings of VoIP to corporations is unquestionable and the future economic benefits of widespread adoption is inevitable. One just needs to review the developments of such products as 'Skype' over the last 12 months to arrive at the realisation of just where VoIP is heading. Companies in Asia have even commenced manufacturing 'Cisco ATA type' devices which interface with skype enabling VoIP calls from your normal PSTN phone. The future of VoIP is cemented and the war for market share is definitely on.
