Our agent-assisted solution dials about 300 contacts/hour, navigates phone menus and gatekeepers, can leave recorded voicemails, and also flags bad numbers or obsolete prospect data. When a prospect answers, VoiceReach™ technology instantly transfers the call to your rep with no annoying delay, and the prospect's information immediately displays on your rep's screen allowing a much richer customer conversation to guide the call. 2-way integration instantly synchs Voicereach with Salesforce™, automatically updating your rep's VoiceReach™ call notes to eliminate manual entry and ensure that valuable marketing data is not lost. -
