Bell Atlantic Corp has begun a six month trial of its new Send-a-Call facility at 250 public payphones in the Washington and suburban Maryland areas, the Teleputing Hotline reports: the service enables payphone callers that get no reply to pay another 25 cents and leave a 30 second message for the called party on the Bell’s computers – after the caller has hung up, the computers will attempt to deliver the message every 15 minutes for two hours, and then every 30 minutes for up to four hours beyond that; it will require Federal Communications Commission approval to go commercial.
