Abstract: Methods and a system of optimizing campaigns are provided. A campaign is identified and associated with a campaign contact list. Moreover, factors which indicate whether a contact during the campaign is a business success or a failure are provided. Further, each contact is associated with one or more demographic attributes. Each completed contact is maintained in a completed contact list and determined to be associated with the success factor or the failure factor of the campaign. A correlation is determined based on at least one of the success factor or the failure factor and one or more of the demographic attributes. A remaining contact list including non completed contacts from the campaign contact list may be sorted based on the determined correlation or logically retrieved and provided to a Call Service Representative.

Abstract: In jamming the data field of a data frame being transmitted at a sending end, a CRC error is caused at a receiving end. To instead avoid such CRC error, a section of bits is inserted into the data frame, so that CRC based on the section of bits is forced to a constant bit pattern. From that point on, all the bits transmitted will be jammed to the constant CRC bit pattern. Thus, any appropriate number of bits (assuming it is at least 32 bits) after that section is the correct CRC based on the jammed data frame. Advantageously, after detecting the ending flag of the jammed data frame, the last 32 bits of the jammed data frame will be the correct CRC at a receiving end.
