I am conviinced that many of these "telemarketing calls" are actually girls from internet porn sites attempts to contact a married husband with perhaps whom they have been "hooking up with". If your guy frequents porn sites, the girls and their "methods of discreet payments" often come like this. If the man answers, he might me asked to put in his "access code" or "VIP code" that he got from the intenet (porn site). Or asked if he would like to "make a payment to his account". Also, TBD could be discreet for a meeting date "to be detemined" another caller ID is "EYEONYOU" 609-318-6034.
Beware and research if your spouse is involved in porn, It is so pernicious and only fools fall for it. They can contact them via any number and make up caller ID's, and they change them each time in attempts to be "discreet".
