Abstract

Apparatuses and methods concerning routing of calls in an IPBX server are disclosed. As an example, one apparatus includes an IPBX server configured to route VoIP calls for a plurality of end-users having respective VoIP-enabled circuit devices communicatively coupled to the IPBX server via a communications network. A call data processing circuit is communicatively coupled to the IPBX server. The call data processing circuit is configured to receive call event messages corresponding to a plurality of end-users from the IPBX server and generate call models from the call event messages. The call data processing circuit also generates call summary metrics from the call models. In response to an input query, the call data processing circuit evaluates the call summary metrics for a parameter of interest specified in the input query to generate data for the parameter of interest.

Dependent claims

An apparatus, comprising:

an internet-protocol private branch exchange (IPBX) server configured and arranged to route Voice over Internet Protocol (VoIP) calls for a plurality of end-users having respective VoIP-enabled circuit devices communicatively coupled to the IPBX server via a circuit-based communications network;
and
a call data processing circuit communicatively coupled to the IPBX server and configured and arranged to
receive from the IPBX server, call event messages indicating a change in status of routed VoIP calls from the IPBX server,
generate call models from the call event messages indicating the change in the status of routed VoIP calls in which the call models have respective data record for each telecommunications link initiated between two participants of the respective calls, including:
generating initial call models based on respective ones of the initiated telecommunication links, and
updating the initial call models over time while the call event messages are received during a duration of the respective calls, by merging additional telecommunication links for the call in the call models;
generate, from the call models, call summary metrics indicative of statistics of the VoIP calls routed;
and
in response to an input query, evaluate the call summary metrics for a parameter of interest specified in the input query to generate data for the parameter of interest.

A method, comprising:

using an internet-protocol private branch exchange (IPBX) server,
routing Voice over Internet Protocol (VoIP) calls for a plurality of end-users having respective VoIP-enabled circuit devices communicatively coupled to the IPBX server via a circuit-based communications network, and
providing call event messages, indicating changes in statuses of routed VoIP calls, to a call data processing circuit communicatively coupled to the IPBX server;
and
using the call data processing circuit:
generating call models from the call event messages that are indicative of changes in the statuses of routed VoIP calls, the call models including a respective data record for each telecommunications link initiated between two participants of the respective calls, updating the call models over time based on the call event messages being received during the respective calls, by merging additional telecommunication links for the call in the call models, and for the respective calls,
generating call summary metrics from the call models,
correlating the call summary metrics with data indicating presence statuses of the plurality of end-users, and
in response to an input query, evaluating the correlated call summary metrics for a parameter of interest specified in the input query to generate data for the parameter of interest.
