An approach provides interdomain traversal to support packetized voice transmissions. A signaling message is received for establishing a voice call from a first endpoint associated with a first domain to a second endpoint associated with a second domain. The first endpoint queries a STUN (Simple Traversal of UDP (User Datagram Protocol)) server to determine information relating to a firewall and network address translator that the first endpoint is behind, and to log into a TURN (Traversal Using Relay NAT (Network Address Translation)) server configured to establish a media path between the first endpoint and the second endpoint. A first proxy server serving the first endpoint communicates with an ENUM (Electronic Number) server to convert a directory number corresponding to the second endpoint to a network address. The first proxy server communicates with a second proxy server serving the second endpoint to establish the voice call. The STUN server, the TURN server and the ENUM server are maintained by service provider. The first endpoint is authenticated to permit exchange of a media stream over the media path. The media stream is relayed, if the first endpoint is successfully authenticated.

Method and system for providing secure media gateways to support interdomain traversal

Example embodiments described herein provide systems and methods for transmitting data packets between a protocol sender and a protocol receiver in a cloud environment, having either the protocol sender or the protocol receiver residing within a virtualized host. A protocol acceleration module may observe the data packets transmitted along the data path between the protocol sender and the protocol receiver using protocol stack configuration information of the protocol sender. The protocol acceleration module may override the protocol stack configuration information with policy-based protocol stack configuration information such that data packets transmitted from the protocol acceleration module to the protocol receiver use the policy-based protocol stack configuration information. For various embodiments, the protocol stack configuration information of the protocol sender is not modified.

Systems and methods are presented for enabling improved communication between one or more communication devices such as mobile wireless devices. The present disclosure provides updatable dynamic, or active, phone book capabilities that provide a user with both contact information as well as dynamic network (web) content that can be updated by communication between a mobile device and a server. The disclosure further provides methods and systems for presence-based message delivery based on a criteria such as presence or identitiy of a caller or caller's device.

System and method for dynamic phone book and network content links in a mobile device

Gateway devices can use dual cellular interfaces to provide reliable communications for client machines. A gateway device can use one of the dual cellular interfaces as a primary interface and the other as a hot backup interface. The backup interface remains connected to a cellular network while communications are routed on the primary interface. Accordingly, the gateway device can rapidly switch communications between from the primary interface to the backup interface. Applications, for example, for ATM payment processing, vending machine telemetry, point of sale payment processing, kiosk internet connectivity, remote monitoring and control, mobile or electronic health, and remote information displays, may run on the gateway devices, on servers, on user devices, or a combination of these devices.

Gateway device for machine-to-machine communication with dual cellular interfaces

The present disclosure generally relates to systems and methods for establishing and maintaining communication between two or more communication devices coupled to communication networks. Some specific aspects relate to communication between a plurality of communication devices each of which is coupled to a respective network. Other aspects relate to establishing such communication by way of contact lists maintained and facilitated on systems coupled to the networks. Users of multiple communication networks, such as VoIP, PSTN and wireless, employ multiple communication devices to communicate with their contacts. For example, a VoIP enabled computer is necessary to access contacts on a VoIP network and a mobile or cellular telephone is used to access contacts on wireless and PSTN networks. A contact list, stored on one communication device, in some instances, cannot be accessed from another communication device. For example, a contact list stored in a VoIP enabled computer cannot be accessed from PSTN or wireless phone devices. Various embodiments described herein provide a convenient solution that can integrate contacts stored on different communication devices and make them accessible from a single device.

Caller-callee association of a plurality of networked devices

The present disclosure describes methods and systems for managing resources, for example in connection with call admission control or other communications or transactions in a system. In particular, a plurality of resource pools are established. At least a first or priority resource is associated with a minimum resource amount, while at least a second or normal resource pool is associated with a maximum resource amount. From the system resource pools, allocations are made to each of a plurality of system servers. If a server receives a request for priority resources that cannot be satisfied from the allocation of priority resources made to that server, that server may borrow from an allocation of normal resources. Resources can also be shared between servers. Accordingly, if required resources are not available from an allocation made to a server receiving the request for resources, that server can request resources from another server. In responding to a request to share resources, a server can attempt to fill the request as if the request had originally been made to that server.

Resource allocation using shared resource pools

The present invention is directed to an architecture 200 for setting up a communication between first and second communication devices 216 and 220 , the first communication device 216 corresponding to a first directing server 224 and first communication manager 204 separate from the first directing server 224 , comprising a contact servicing agent 244 operable to (a) receive a call set up message at least one of addressed to and originated by the first communication device 216 ; (b) determine that the first communication device 216 has a corresponding first communication manager 204 ; (c) forward the call set up message to the first communication manager 204 and request the first communication manager 204 to perform at least one of call originating and terminating processing; and (d) rout the call set up message to a destination referenced in the call set up message.

Originator based directing and origination call processing features for external devices

Methods, devices, and systems are provided for identifying unique points in communication processing for substituting and restoring identities associated with the communication. These specific replacements facilitate communication requests to-and-from external identities to be treated similar to communication requests to-and-from enterprise users, thereby allowing enterprise users to access enterprise-based communication preferences and services via non-enterprise devices.

Network framework associating non-enterprise phones with enterprise users

Methods, devices, and systems for controlling access to a password protected resource are provided. More specifically, different communication profiles can be mapped to a single user and that user can utilize a single password to gain access to the password protected resource using any one of his/her communication profiles. Each communication profile may have a unique authentication value associated therewith, but each unique authentication value may be determined based on the single password, thereby eliminating the need for a user to remember multiple passwords for each of his/her communication profiles.

Sip digest authentication handle credential management

In one embodiment, a communication device includes an outgoing call alerting agent 196 that (i) detects that a communication device has entered an off-hook state and that a first line appearance has been selected by a user for an outgoing call, (ii) forwards a first call setup message to a third party call controller, the call setup message including a request to reserve the first line appearance for the outgoing call, and (iii) thereafter collects a set of digits dialed by the user for the outgoing call and provides the collected set of digits to the third party call controller.
