A system and method for an on-line web-based advertiser-broker to subsidize calls of a plurality of VOIP operators' subscribers by showing them video advertisements from a catalogue of advertisements provided by a plurality of advertisers. The advertisement is shown by the advertiser-broker and then the call is transferred to the VoIP operator for call completion. The advertiser-broker provides the clearing-house services between many advertisers and many VoIP operators, subsidizing wholly or partially phone calls of users of VoIP operators by showing them streaming video advertisements of advertisers who pay for the calls. With this new business, phone calls get monetized through advertisers while users pay nothing for phone calls, and VoIP operators do not need to incorporate advertisers to their business.
