A differentiated routing system includes an electronic service in communication with an ingress gateway that receives a communication service, such as a call from a terminal, over a trunk. The service receives a request from the ingress gateway for establishing a communication service for the calling party terminal. The service obtains information associated with the calling party terminal, which may be based on the trunk and its relationship to a customer, in which the information is to be used for applying at least one of a routing decision and policy decision to the communication service, and appends a tag to the request based on the information. The service may then transmit the request appended with the information to a routing device, which may then use the information when providing the service.

In an example embodiment, a solution that allows a PBX to utilize bridged mobile or desktop applications for collaboration and softphone use is provided. The solution works in conjunction with existing hardwired PBX devices without requiring additional hardware such as an edge router to be integrated with the PBX hardware. Incoming calls are able to ring a user's hardwired device, such as a desk phone at an office, while simultaneously ring mobile device or desktop applications (apps). App users can place outbound PSTN calls and dial PBX extensions just as if they were using their hardwired device. Additionally, PSTN services are utilized from the existing PBX rather than bypassing the existing PBX, which makes tracking and billing more straightforward. A Session Initiation Protocol (SIP) tie trunk is used between the existing PBX and a software bridge controller.

A method of processing call setup signalling at a telecommunications switch. The telecommunications switch receives call setup signalling, comprising at least a caller ID. The telecommunications switch is connected via a plurality of trunks which connect the telecommunications switch to two or more other telecommunications switches capable of transmitting call setup signalling to the telecommunications switch. The telecommunications switch detects at least one of the plurality of trunks via which the call setup signalling has arrived at said telecommunications switch. The telecommunications switch determines a call handling option to be applied to the incoming call setup signalling based at least in part on the detecting and the caller ID.

Novel tools and techniques are provided for implementing application programming interface (API)-based concurrent call path (CCP) provisioning. In various embodiments, in response to receiving a CCP provisioning request, a computing system may determine whether such a request would affect a set of trunk groups assigned to a customer based at least in part on network utilization data. If not, the computing system may cause the nodes in the network to increase or decrease, in near-real-time, the number of CCPs in at least one trunk group assigned to the customer based on the CCP provisioning request. If so, the computing system may cause the nodes in the network to increase or decrease, in near-real-time, the number of trunk groups assigned to the customer and may cause the nodes in the network to increase or decrease, in near-real-time, the number of CCPs in the updated number of trunk groups.

Aspects of the present disclosure involve systems and methods for providing routing of a communication received at a telecommunications network based on a unique identifier. In particular, a telecommunications network may route one or more communications based on a dynamically updated trunk group identifier associated with an egress user. Thus, in addition to routing the communication based on a telephone number or Internet Protocol (IP) address associated with a user, the network may also route the communication based upon a dynamically updated trunk group identifier included in an updated routing function of the network.

A communication device includes: a signal generator configured to generate a first signal and supply the first signal to a telephone line; a terminator having a variable terminal impedance as seen from the telephone line; a detector configured to detect a difference between the terminal impedance and a line impedance of the telephone line; and a controller configured to determine the terminal impedance so that the difference is reduced.

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.
