System and method of admission control of a communication session

A method comprising:

• receiving a first communication session initiation request comprising, an originating device identifier;
• processing the first communication session initiation request to establish a first communication session between an originating device associated with the originating device identifier and a target device;
• storing a data record comprising one or more data entries of information about the first communication session between the originating device and the target device;
• determining one or more attributes relating to the originating device identifier based on the one or more data entries of the data record;
• determining that the one or more attributes satisfy a communication threshold that indicates the originating device identifier is associated with a possible autodialing system;
• and
• responsive to determining that the one or more attributes satisfy a communication threshold, tagging the originating device identifier as a possible autodialing system.

A method comprising:

• processing a plurality of communication sessions initiated by an originating device associated with an originating device identifier;
• determining that a communication threshold for the originating device identifier has been satisfied based on analyzing a data record comprising one or more attributes for each of the plurality of communication sessions;
• retrieving audio content from one or more of the plurality of communication sessions;
• converting the audio content to text data and comparing the text data to a database of keywords to determine that the communication session is invalid;
• and
• responsive to determining that the communication session is invalid, blocking one or more future communication sessions associated with the originating device identifier.
