Methods and systems are described for distributing and receiving fax transmissions via a data connection that is owned by a service provider. In one embodiment, a fax server receives a signaling protocol invite from a telephone service provider in response to the telephone service provider receiving, over a circuit switched network and from a source device, an incoming call signal to a fax telephone number of the service provider. The server responds to the invite by establishing a data connection based on the signaling protocol with the telephone service provider, where the data connection is owned by the service provider. The server receives an incoming fax message that is in a fax format and is routed by the telephone service provider as the source device transmits the incoming fax message. The server transmits the fax message to a destination address.

A method for a seamless transfer of a secure multimedia conference session from one endpoint device to another without a need to rekey the session is provided. In this method, a first endpoint device connects a participant to a multimedia conference session to which at least one other participant is connected and based on detecting one or more second endpoint devices within a predetermined location proximity of the first endpoint device, determines whether to transfer the multimedia conference session to a target endpoint device. Based on determining that the session is to be transferred, the first endpoint device establishes a secure pairing connection directly with the target endpoint device and provides, via the secure pairing connection, information about the multimedia conference session based on which the multimedia conference session is transferred to the target endpoint device without rekeying the multimedia conference session.

A telecommunication device for real-time communication at a border between a global transport network and a private domain of a communication network may include a proxy for a communication protocol, means for traffic using real-time communication protocols to traverse a firewall, means for real-time traffic initiated by the communication protocol to traverse a firewall, means for measuring and collecting value information about the real-time traffic over the global transport network, means for creating mutual trust between the telecommunication device and a second device with which it communicates; and means for authorizing usage of a feature for a mutually trusted communication participant.

In a cellular system having both 4.sup.th-Generation (4G) and 5.sup.th-Generation (5G) cellular networks, cellular device sends a Session Initiation Protocol (SIP) INVITE message to initiate a voice call. The message is received and acted upon by a Proxy-Call Session Control Function (P-CSCF) of an IP Multimedia Subsystem (IMS). Cellular devices that support 5G services are configured to include an information element (IE) in the SIP INVITE message to indicate support for 5G services. When responding to a SIP INVITE message, the P-CSCF determines whether the SIP INVITE message includes such an IE. If the SIP INVITE message contains an IE indicating 5G support, the P-CSCF sends an Authorization Authentication Request (AAR) message to a 5G Policy Control Function (PCF) to initiate a 5G dedicated bearer. Otherwise, the P-CSCF sends the AAR to a 4G Policy and Charging Rules Function (PCRF) to initiate a 4G dedicated bearer.

A system is provided for providing communication event routing and transfer capability in a multi-site communication-center environment. The system utilizes a presence protocol application and a routing application for determining availability of an agent or system and for setting up the transfer from a point of transfer on a network to a destination of transfer on the same or connected network. In a preferred use the presence protocol application is shared by communication-center sites cooperating in the transfer and routing of events and the presence protocol enables at least one event-handling process normally performed by the routing application.

A method is disclosed for managing a plurality of resources in a media gateway, the method comprising: determining that a utilization of a resource exceeds a first threshold, wherein the resource is one of the plurality of resources; determining a reduction in load to communicate to a media gateway controller (MGC) coupled to the media gateway, wherein the reduction is based on the resource and the first threshold; and sending a message indicating the reduction and the resource to the MGC.

A method includes, with a first bearer node of a telecommunication component, utilizing network connections between the first bearer node and a first plurality of control nodes of the telecommunication component, the bearer node configured to process media data being transmitted between endpoints over a network. The method further includes, with a second bearer node of the telecommunication component, utilizing network connections between the second bearer node and a second plurality of control nodes of the telecommunication component, the second plurality of control nodes having at least one control node in common with the first plurality of control nodes and at least one control node not common with the first plurality of control nodes.

VoIP networks and methods are disclosed for distributing media resources in a VoIP network for providing services. VoIP endpoints, media gateways, and/or other network nodes in the VoIP network report available media resources (i.e., available processing capacity) that are able to provide services, such as providing announcements, DTMF digit collection, etc, to a distributed resource server. The distributed resource server then assigns the available media resources among the VoIP endpoints and/or media gateways to perform services for calls in the VoIP network in order to distribute the tasks of performing services among different nodes of the VoIP network.

There is proposed a mechanism for a connection control conducted in a communication network (such as IMS) when a back to back user agent (B2BUA) and network address translation function are involved in the establishment of the connection. When a control network element, such as a P-CSCF, receives a signaling message related to the establishment of the communication connection, via a communication leg coming from a network address translation device, it is determined whether address information contained in an SDP element of the signaling message matches with preset address information allocated to a border gateway function or BGF. When no matching is determined, normal processing like an initiation of a latching procedure at an own BGF is conducted. Otherwise, if a matching address information is determined, i.e. a mirrored SDP is deemed to be present, a latching processing at an own BGF is inhibited and the received BGF's address information are used in the connection establishment procedure. This processing is conducted at all session ends coming from the B2BUA, so that a communication connection with media flow can be established through pinholes of the BGF(s).
