  • Publication number: 20130022193
    Abstract: Methods and systems for determining call types are described herein. An intelligent node is configured to determine whether a call is a mobile-to-mobile call between subscribers of a telecommunication service provider based on a response to a request from the intelligent node. The intelligent node may further be configured to send a state request to an interconnecting network of the telecommunication service provider. A node of the interconnecting network determines whether a serving subscriber identifier is included in a routing database of that node. If the identifier is not included, the node responds with an error message. If the identifier is included, the node communicates with a relay function and responds to the request with a state received from the relay function. The intelligent node may also be configured to send an ENUM query and receive an identifier of the telecommunication service provider associated with the serving subscriber.

  • Patent number: 8233591
    Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

  • Patent number: 8102989
    Abstract: Gateways facilitate communication of voice traffic from a calling party to a called party over a packet network. To establish a communication session, an originating gateway sends one or more initial call control messages using overlap signaling to a destination gateway. The destination gateway may be unable to establish the communication session using overlap signaling. The destination gateway signals the originating gateway, such as by indicating that the communication session could not be established because of an incomplete or invalid destination address. The originating gateway then attempts to establish the communication session using en bloc signaling. In this way, an attempt that fails due to the use of overlap signaling is retried using en bloc signaling.

  • Publication number: 20110182281
    Abstract: In a third party call control system, a controller sends a command to a PBX for causing the PBX to initiate setup of a call leg between the PBX and a telephone device. The PBX responsively places a telephone call to the telephone device and sends an indicator to the controller that the call is in a ringing state. Responsive to the indicator, the controller subscribes with the PBX for event notification of DTMF tones from the telephone device for verifying the setup of the call leg. Configuration of the PBX for providing the desired event notification to the controller may thus be completed before any DTMF tones arrive at the PBX. This may be true even if an audio channel of the telephone call is established before the PBX receives any indication that the call was answered. Verification of call leg setup by the controller may thus be facilitated.

  • Patent number: 7916857
    Abstract: The subject matter described herein includes methods, systems, and computer program products for selectively processing or redirecting SCCP messages. According to one method, an SCCP message addressed to an STP and sent route-on-PC-SSN is received at the STP. It is determined whether the SCCP message can be processed locally by the STP. In response to determining that the SCCP message can be processed locally by the STP, the SCCP message is terminated, processed locally, and a response is sent to the message originator. In response to determining that the message cannot be processed locally at the STP, the SCCP message is redirected to a destination.
