The present invention facilitates identification and control of peer-to-peer sessions via an access concentration point (ACP). The ACP will monitor packets routed therethrough and detect access messages intended for known peer-to-peer access services. The access messages sent from a communication client to the peer-to-peer access service, which will respond by sending an access reply message back to the communication client. The ACP will monitor the packets being routed to identify the access reply message, which will include routing addresses that may be associated with potential remote communication clients. With these addresses, the ACP can monitor packets to identify when an attempt to initiate a peer-to-peer communication session is being made to or through an entity associated with one or more of these addresses. Upon detecting a session initiation message to or through an identified address, the ACP may take any number of actions, depending on how the ACP is configured.
