We Buy Un-Wanted Calls!

Call Delivery Systems is an advertising and research call management platform.  We buy unwanted calls from telecom providers and invite the caller to hear an advertisement or participate in a research study. Unwanted calls include misdials to unassigned numbers/idle inventory and press 2’s .  We turn write-offs into revenue for telecom providers by paying the MRC and the per minute rate for these Unwanted calls.

Telecom providers traditionally handle unwanted calls by playing dead air or playing a message such as, “Your call cannot be completed as dialed” and then ending the call. But, instead of playing dead air or a message, telecom providers now instantly transfer millions of these calls to the Call Delivery Systems soft switch and IVR (Interactive Voice Response) platform.

About Call Delivery Systems

Learn More

U.S. and Canadian telephone carriers route in excess of 150 billion calls per month, 5 to 10 billion of which never connect to their intended destination. Traditionally, failed call attempts referred to as MIDI calls™ (misdials, incomplete, disconnects, inbound) – end up in phone network oblivion, representing a missed opportunity and possibly unwanted costs. Often the recipient of these “wrong number” calls, via its bank of more than 200,000 toll-free numbers, Call Delivery Systems has figured out a way to turn these mistakes into a business opportunity through its proprietary platform.
