Playback of multimedia data associated with a recorded conference session is simplified, particularly for a person who participated in the conference session from a mobile device. At a recording server that is in communication with a plurality of endpoints in a conference session, multimedia received from the plurality of endpoints participating in the conference session is recorded. The recording server obtains geographical location information for at least one mobile endpoint participating in the conference session as the at least one mobile endpoint moves. The recording server temporally correlates the geographical location information for the at least one endpoint with recorded multimedia data for the conference session. The recording server stores data tags for the geographical location information for the at least one mobile endpoint in association with the recorded multimedia data for subsequent use in indexing to map data to retrieve a portion of the recorded multimedia data for playback.

Geographical location information/signal quality-context based recording and playback of multimedia data from a conference session

Techniques are provided for using a location of a caller placing a call that is received at a call center to identify other sources of information that are relevant to the call. A call is received at a call center from a caller. The location of the caller is obtained from the received call, and other sources of information potentially relevant to the call are identified based on the location of the caller. For example, information is stored that identifies at lease one individual that is proximate to the location of the caller, and communication is initiated with at least one individual who is determined to be located proximate to the caller.

Call to call center as trigger to capture and record other geographically relevant data

Techniques are provided for receiving multimedia from a plurality of endpoints participating in a conference session, including multimedia from an endpoint that was muted during the conference session. A muting state is detected at a particular endpoint during the conference session and the multimedia from the particular endpoint is recorded even though it is not forwarded and rendered to the other endpoints during the conference session. Information associated with the multimedia data for the conference session is stored to indicate the time period during which the muting state was detected at the particular endpoint. Techniques are also provided for granting access at a later time to the stored multimedia data for conference session, including access controls to the muted multimedia.

Capturing and controlling access to muted content from a conference session

After completion of a voice-over IP call, for example, first information representing a Layer 3 path of a packet flow of a completed call that has passed through a packet-switched network is created. Second information representing a Layer 2 path of a packet flow of the completed call is also created. One or more selected phone call detail records are retrieved, which are associated with the completed call. Thus, the likely path of a troubled call is determined, and phone call detail records associated with key points in the path are located. The first information, second information, and selected phone call detail records are provided to a user for use in evaluating one or more problems experienced in the completed call.

Method and apparatus for determining troubleshooting information for completed calls in a telecommunications network

A method is disclosed for creating and storing troubleshooting information for diagnosing one or more problems experienced in one or more completed voice calls that are carried by a packet-switched data network. After completion of a voice-over IP call, for example, first information representing a Layer 3 path of a packet flow of a completed call that has passed through the data network is created and stored. Second information representing a Layer 2 path of a packet flow of a completed call that has passed through the data network is also created and stored. From a phone call detail record database, one or more selected phone call detail records are retrieved, which are associated with the completed call from a database of phone call detail records for a large plurality of completed calls. Thus, the likely path of a troubled call is determined, and phone call detail records associated with key points in the path are located. The first information, second information, and selected phone call detail records are provided to a user for use in evaluating one or more problems experienced in the completed call. Based on this information, the user can troubleshoot the call and identify responsive action. In one embodiment, IP path segments of the voice over IP flow are identified and media termination points are identified for each path segment. Layer 2 and Layer 3 path tracing is performed for each IP segment of the voice over IP flow.
