    Abstract: Embodiments disclosed herein provide systems and methods for recording WebRTC communications at a network edge. In a particular embodiment a method provides, in an edge system of a communication network, receiving identification information that identifies a first endpoint and a second endpoint between which a first WebRTC communication will be established. The method further provides establishing the first WebRTC communication between the first and second endpoints through the edge system using the identification information. Also, the method provides identifying packets for the first WebRTC communication and recording the packets to a storage system.

    Abstract: The system and method monitor a secure Web Real Time Communication (WebRTC) session between browsers. To do so, a WebRTC application receives a first WebRTC offer with a fingerprint of a first browser to establish a secure communication session. The WebRTC application sends session information and the fingerprint of the first browser to a media relay. The WebRTC application receives a fingerprint of a media relay. A second WebRTC offer with a fingerprint of the media relay is sent to a second browser. An answer to the second WebRTC offer is received. Session information and the fingerprint of the second browser are sent to the media relay so the media relay can decrypt the secure communication session. The first WebRTC offer is answered. A secure communication session is established via the media relay using the fingerprints. The media relay, based on the fingerprints, can monitor the secure communication session.

    Abstract: Embodiments disclosed herein provide systems and methods for quarantining communications at a network edge by routing traffic through a specialized network edge system. In a particular embodiment a method provides, identifying criteria indicating whether certain network traffic should be handled by the specialized network edge system. The method further provides receiving first information about first network traffic received at a first network edge system for a communication network. In response to determining, based on the first information, that the first network traffic satisfies the criteria, the method provides routing the first network traffic through the specialized network edge system.

    Abstract: To determine the correct media stream to latch onto, the system and method uses a hashing algorithm to uniquely identify a legitimate media stream. A first invite message is received at a Session Border Controller (SBC) to establish a communication session. For example a Session Initiation Protocol (SIP) INVITE is received. The first invite message comprises a first hash of a fingerprint. For example, the hash may be a hashed session key. A media message is received that contains the fingerprint to establish a media stream for the communication session. A second hash is created using the fingerprint in the media message. The first hash is compared to the second hash. In response to the first hash matching the second hash, a Network Address Translator (NAT) latches to an address and/or a port in the media message. Thus, the correct media stream is associated with the communication session.

    Abstract: Embodiments provide systems and methods for exchanging media through an edge server between different communication networks. More specifically, embodiments of the present disclosure provide systems and methods for establishing and conducting voice and/or video communications between one or more parties on a private network, such as within an enterprise, and one or more parties on a different network such as another private network or an open network such as the Internet using an edge server of the enterprise network. This edge server, also referred to herein as a Session Border Controller (SBC), can be adapted to allow media packets to traverse through a port typically kept open by enterprise firewalls and used for other data exchanges such as HyperText Transfer Protocol (HTTP) data traffic. The SBC can also provide multiplexing and demultiplexing of media streams through the same port and address to traverse firewalls between the different communication networks.
