04. Using SIP to Defeat Robocalling
Presented by Mark Lindsey, ECG.
When the phone rings, is it a human being or a robocall? The expensive PSTN once ensured calling was too expensive for practical robocalls, but the efficiencies of deregulation -- and VoIP -- have brought pre-recorded advertisements to every telephone.
