Circuit domain disturbance call non-inductive replacing method

The invention relates to a circuit domain disturbance call non-inductive replacing method. In the disturbance video detection process, non-inductive replacing processing is performed on session data of an H.245 negotiation audio and video AL format with extraction of a reuse table. A reuse table acquisition method and a videophone audio and video replacing initiation scene are not limited. A problem of frame stagnation generated in the videophone replacing interception process can be effectively solved on the basis of the message structure and the transmission characteristic of reuse data contents in videophone transmission and on the basis of an H.223 protocol. Data of both communication sides are monitored, captured and modified and replaced between nodes of the transmission path of both session communication sides so that the replacing effect is great.
