Abstract
A method and system of sending supplemental information during a telecommunications session includes the step (305) of detecting a period of silence within the telecommunications session. The period of silence can be detected from at least one member of the telecommunications session. Comfort noise can be specified within at least one time slot (205) of a plurality of consecutive time slots (205, 210) for a channel over which the period of silence is detected. For at least one other time slot of the channel (210), non-voice data is specified such that the channel includes both comfort noise and other non-voice data during the period of silence. The consecutive time slots (205, 210) can be associated with a data block (200). The non-voice data can be a data payload of the other time slot (210).
