Systems and methods presented herein provide for real time communications between service provider subscribers. In one embodiment, a web server is operable to provide a network-to-network interface (NNI) with a plurality of service providers, to communicate with the service providers through WebRTC links, and to retrieve contact information of subscribers to the service providers over the WebRTC links. The web server also includes a database operable to store the contact information of the subscribers. The web server is also operable to process a connection request from a first of the subscribers to connect with a second of the subscribers, to retrieve the second subscriber's contact information from the database, to push a notification message to a device of the second subscriber using the second subscriber's contact information (e.g., a user identity), and to establish a WebRTC connection between first and second subscribers when the second subscriber accepts the connection.

The obfuscation of information included in Session Initiation Protocol (SIP) invites for the purposes of facilitating Lawfully Authorized Electronic Surveillance (LAES) is contemplated. The obfuscation may include the use of LAES headers with invites of sessions that require surveillance as well as those not requiring surveillance and/or selecting values or otherwise influencing parameter selection of data included in LAES headers according to a validity function, a shared secret, a key or other construct.

Obfuscation of lawfully authorized electronic surveillance

Facilitating Voice over Internet Protocol (VoIP) phone calls where at least a portion of the phone call relies upon signaling exchanged as part of a Session Initiated Protocol (SIP) session conducted through a SIP Private Branch Exchange (SIP-PBX) is contemplated. Caller-ID and/or security measures may be implemented to enable caller-ID when the SIP-PBX is untrusted.

Caller-ID for redirected calls from SIP-PBX

A method and system of controlling state for devices operable to support signaling or sessions between endpoints, such as the type used to support phone, video, messaging, and other calls. The state control may include transitioning the device between in-service and out-of-service states as a function of current, past or future operating demands on the devices.

Method and system of controlling state devices operable to support calls between endpoints

A method and system of managing end-to-end loss in a manner that allows phone calls to be executed across many networks at desirable end-to-end loss levels, including networks having fixed-loss stratagems, by controlling devices to adjust their local loss or gain in order to establish target end-to-end loss.
