Methods and apparatus to select a dynamically peered voice over Internet protocol (VoIP) border element are disclosed. An example method comprises collecting data representative of a dynamic performance of a voice over Internet protocol network, prioritizing a selection of a peered border element based on the collected data, and modifying a telephone number mapping (ENUM) database based on the prioritized selection.

Providing a voice call includes: receiving, from a user equipment (UE), a request to initiate a voice call traffic session; requesting setup of a voice call data pipe; based on at least a setup of the voice call data pipe not completing prior to a timer event, transmitting voice packets over a signaling data pipe; and based on at least the voice call data pipe setup completing, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe. Placing a voice call includes: requesting, by the UE, to initiate the voice call traffic session; based on at least a first trigger event, transmitting voice packets over the signaling data pipe; and based on at least a second trigger event, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe.

An ingress call filter system enables real-time or near real-time efficiencies of an inter-carrier switch. The ingress call filter determines if a received call to a called party is likely to fail. If the call is likely to fail, the ingress call filter returns an indication that the call should be filtered or rejected. If the call in not likely to fail, the ingress call filter returns an indication that a call router should attempt to establish the call. Such techniques mitigate penalties assessed to the inter-carrier network for incomplete or failed calls in real time or near real time.

The present invention comprises systems and methods for controlling a connection between and IT infrastructure and a telephony network. In one embodiment, the present invention allows such control through the use of application services adapted for use with a telephony network, a telephony application server that exposes the telephony network to the application services, and a service mediation platform controlling the interaction between the application services and the telephony application server. The service mediation server may comprise a user profile manager for handling the user profiles of a subscriber database, a service level agreement manager for invoking a set of application services, and a resource policy enforcement manager for managing the resources of the telephony network.

A conference call management method, system, and computer program product include inferring an Internet Protocol (IP) address of a new user requesting to join a call including at least one other user, inferring a codec to stream an emulated network pattern for the call if the new user were to join the call, measuring a call quality perceived by the at least one other user in the call while the emulated codec is run on the call, and measuring an impact on the call quality in a case that the new user joins the call based on the perceived call quality and the network pattern.

Various embodiments provide for a way of routing messages using location routing numbers. More specifically, some embodiments can route calls on different legacy networks by using features of existing telecommunication policy and databases. For example, a location routing number can be registered in a number portability administration center database. The location routing number may be in a native number block of a facility carrier and a company registering the location routing number in the number portability administration center database may not be the facility carrier. The destination switch of the facility carrier can be programmed to accept traffic associated with the location routing number. As a result, components of the network can route the message for the company to a destination switch of the facility carrier.

The disclosed system enables a wideband codec audio call between a mobile device and a wireless telecommunication network support center by ensuring that multiple components of the network participating in the call and multiple legs that make up the call all communicate using the same wideband codec. A leg among the multiple legs is a connection between two components participating in the call. While all the legs making up the call between the caller and the callee have to be wideband, the system can enable any branching legs in the call, for example, those directed to a third party, to be either wideband or narrowband.

A method of extending calls includes receiving a request to establish a call session with a called party, and establishing the call session between the calling party and the called party. The method further includes monitoring the length of the established call session, and receiving a message requesting a termination of the call session. Still further, the method includes, in response to receiving the message requesting the termination of the call session, maintaining the established call session for an additional time period, wherein the additional time period plus the monitored length of the established call session is equal to or greater than a threshold of time.

To maximize efficiencies and to reduce termination costs of inter-carrier exchanges, an auto-dialer detection system enables an inter-carrier network switch to detect, in real-time or in near real-time, calls that are originated by auto-dialers. A call router of the switch may receive an incoming call attempt that includes a particular Automatic Number Identification (ANI). The auto-dialer detection system allows for a real-time or near-real time determination, based on the ANI and contents of a cache during a sliding window of time coincident with the reception of the origination, whether or not the call should be routed through the switch. Further, the auto-dialer detection system provides a real-time or a near real-time update to the cache contents to enable further real-time or near-real time detection and blocking of auto-dialed calls. Overrides to the cache (e.g., to always allow and/or to always block calls that include certain ANIs) may be provided.
