Novel tools and techniques are provided for implementing programmatical public switched telephone network (“PSTN”) trunking for cloud hosted applications. In various embodiments, a computing system may determine one or more first network interconnection characteristics associated with a first entity service provider within a call service network operated by a call network service provider. Based on the determined one or more first network interconnection characteristics associated with the first entity service provider, the computing system may cause a network provisioning application layer to establish one or more network interconnections between a first network associated with the first entity service provider and the call service network, in some cases, by establishing shared peering connections between the first network and the call service network. The shared peering connections may enable a plurality of customers of the first entity service provider to establish call service connections that are shared over the shared peering connections.

A virtual collaboration system provides communication between a plurality of participants via a collaboration session that includes a corresponding plurality of participant devices. The collaboration session facilitates communication between the participant devices via a plurality of communication channels over which the participants communicate. For example, in some embodiments, the channels include one or more of a video channel, audio channel, or document sharing channel. A participant designates in which of the plurality of channels they will participate, and the designations are communicated to other participants. This provides a broader understanding of each participant's circumstances and ability to engage across the different channels with the plurality of participants.

Apparatus and methods concerning call routing are disclosed. In an example embodiment, a call alert message, indicative of the call answer options, is communicated from a data-communications server to the communication device, determined in response to receiving an incoming call for a communication device at the server. A selected option is received from the communication device. In response to the selected option indicating the first call answer option, the call is routed to the communication device as a call via a data network or in response to the selected option indicating the second call answer option, the call is routed to the communication device via a PSTN.

One example method may include identifying a call notification of a call intended for a mobile device, retrieving call data having a code object identifier with the call notification, forwarding the call data with a code object to the mobile device based on the code object identifier prior to forwarding the call, and forwarding the call to the mobile device.

A secure phone system comprising a plurality of Voice over IP (VoIP) phones, each having an enhanced security implant device, a Mutual Disabling Unit (MDU) and a method of operating the system for securing VoIP phones located in the same room by disabling a VoIP phone while a call is active in another phone in order to prevent audio eavesdropping.

Disclosed in embodiments of the present disclosure are a communication method and apparatus, and an electronic device. A specific implementation of the method comprises: in response to a call initiation operation of a multimedia conference, determining a candidate object of the multimedia conference according to an object targeted by the call initiation operation; and displaying, on a multimedia conference interface of the multimedia conference, call state information for the candidate object.

Various embodiments may include methods and systems for avoiding connecting an illegitimate call within a telecommunications network. Various embodiments may include receiving, from a telecommunications network, an incoming call initiating message notifying the first wireless device of an incoming call, in which the incoming call initiating message includes caller information. Some embodiments may further include transmitting a provisional response message including callee information of the first wireless device in response to receiving the incoming call initiating message, transmitting a request message to a second wireless device based on the caller information and the callee information, determining whether the second wireless device initiated the incoming call based on a response message from the second wireless device, if received, in response to the request message, and taking an action to prevent connection of the incoming call in response to determining that the second wireless device did not initiate the incoming call.
