The embodiments described herein recite a telephone communication system used for handling information such as messages, typically voice mail messages, and, more particularly, is directed to a system that provides distributed session initiation protocol (SIP) silos. Distributed SIP silos (DSS) is a Communications Application Platform (CAP) feature that maintains the site's call capacity even when a signaling server fails. DSS uses multiple non-redundant signaling servers to provide SIP signaling for the same set of media ports. Because there are multiple signaling servers providing signaling for the same set of ports, the failure of one signaling server only terminates the calls it was actively processing and once those calls have been cleaned up, all the available (non-suspended) ports in the configuration are available to the remaining signaling servers.

The present disclosure is directed to a system for device configuration-based function delivery. A server receives a data structure including device configuration information that indicates the computing device comprises an application programming interface to allow a data function to access a call function of the computing device. The server identifies a first content item having a call-on-select function and a second content item without a call-on-select function. The server determines, based on the device configuration information, a first call score for the first content item having the call-on-select function and a second call score for the second content item without the call-on-select function. The server selects the second content item for transmission to the computing device to cause the computing device to display the second content item without the call-on-select function on the computing device comprising the application programming interface.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium in a telephone having computer instructions to execute a web server application in the telephone. The web server application can be operable to detect an incoming plain old telephone service call, identify a calling party identifier from the incoming plain old telephone service call, and direct one of a plurality of devices detected by web server application to present the calling party identifier. Other embodiments are disclosed.

A method and system for operating a multitenancy telephony system including receiving a plurality of call requests associated with an application server; selecting a subset of the received call requests using a load balancer; assigning each selected call request to one of a plurality of resources creating, on the assigned resource, a call session for each selected call request; and coordinating the created call sessions resulting from the selected subset of the received call requests associated with the application server.

Methods and systems directed to retrieving voicemails from a voice mailbox server. In particular embodiments, a mailbox server may receive a notification from the voice mailbox server and connect to the voice mailbox server providing the credentials of a client device, and pull new voicemails for storage at the mailbox server. In particular embodiments, mailbox server periodically polls voice mailbox server for new voicemail messages. In particular embodiments, a client device polls or receives notification of new voicemails, and transmits a downloaded message to the mailbox server.

Apparatus and methods concerning routing of calls in an IPBX 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 devices communicatively coupled to the IPBX via a network. A user-activity detection circuit is communicatively coupled to the IPBX server. The user-activity detection circuit is configured to receive activity data indicating activity of end-users in a virtual office environment and receive event messages indicating statuses of pending calls in the IPBX server. The user-activity detection circuit determines user-activity statuses of the end-users based on received activity data and event messages. A computing server is communicatively coupled to the user-activity detection circuit and is configured to provide a set of services for one or more of the plurality of users as a function of the determined user-activity statuses of the end-user.

Caller Name Identification, or CNAM Caller ID, is a telecommunication end-user feature that appeared for PSTN landline customers in the late 1980s. The rapid development of cellular mobile and VOIP telephony systems lead to the frequent omission of the CNAM Caller ID feature. Described is an independent end-user system that obtains the CNAM Caller ID after the call page transmission. The system operates on the user's smartphone or on a TCP/IP connected computer. A user with multiple telephone devices (i.e. a smartphone, landline, and VOIP line) may share use of this system between all devices.

Apparatus and methods concerning routing of calls in an IPBX 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 devices communicatively coupled to the IPBX via a network. A user-activity detection circuit is communicatively coupled to the IPBX server. The user-activity detection circuit is configured to receive activity data indicating activity of end-users in a virtual office environment and receive event messages indicating statuses of pending calls in the IPBX server. The user-activity detection circuit determines user-activity statuses of the end-users based on received activity data and event messages. A computing server is communicatively coupled to the user-activity detection circuit and is configured to provide a set of services for one or more of the plurality of users as a function of the determined user-activity statuses of the end-user.

A computer-implemented method is disclosed for integrating at least one first communication terminal assigned to a user as a preferred device in a static configuration of a communication system and/or for dynamically switching from a first communication terminal used as a preferred device to a second communication terminal as a preferred device for providing a one-number service using the preferred device, to which a one-number service number is assigned, wherein at least two communication terminals are statically assigned to the user and a preferred device is also dynamically assigned to the user through a virtual device. Also disclosed is communication system designed for this purpose.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium in a telephone having computer instructions to execute a web server application in the telephone. The web server application can be operable to detect an incoming plain old telephone service call, identify a calling party identifier from the incoming plain old telephone service call, and direct one of a plurality of devices detected by web server application to present the calling party identifier.
