A system and method for notifying a called party of a call attempt is provided. The method comprises initiating a communication request by a calling party; routing the communication request to an intelligent network via an mobile service center; validating the communication request by the intelligent network; and handing over the communication request to an intelligent platform by the intelligent network in the event of a nonstandard trigger event such as calling party insufficient balance. The processing of communication request by the intelligent platform includes monitoring number of call attempts, introducing a delay in sending notification, monitoring availability of called party and performing one or more actions based on the delay and the availability of the called party.

Enhanced capabilities within a telephone network are made accessible to a telecommunications device. The telecommunications device is used to dial a sequence. A network server receives and identifies the sequence invokes an advanced network function. A advanced network function server in communication with the network server provides instructions as to how the network server is to provide the advanced network function. The network server processes the call in accordance with the received instructions to provide the particular advanced network function.

Asynchronous and/or synchronous zero charge telephony protocol systems and methods may include an asynchronous signaling switch and/or a call duration time quota from a synchronous charging onset to place and complete a call. A call request is received with a second device mobile address. The asynchronous systems include instructions to automatically modify the mobile address with a routing prefix when the first device has insufficient balance or independent of balance, route to the asynchronous signaling switch based on an associated modified address trunk path, revert to the call signal at the asynchronous signaling switch, and deliver and automatically disconnect the call immediately when the call is completed. The synchronous systems include instructions to automatically set the call duration time quota upon insufficient balance, and deliver and automatically disconnect the call from the second user mobile device when the call is completed and the call duration time quota is exceeded.

A method and system for providing a second line service (SLS) feature to a subscriber using a telecommunications device (TD) which includes receiving at a switch on the network of the subscriber's primary service provider a communication made up of a trigger and a directory number. When the communication is received at the primary service provider's switch, the switch parses the communication and detects the trigger. Once the switch has received the communication, the switch additionally transmits a query message to a SLS platform that manages the SLS feature. As a result of the switch's query message transmission, the switch receives a reply to the query message from the SLS platform. Based at least in part on the reply to the query message, the switch can route the communication such that the switch connects one or multiple voice channel circuit between the subscriber's TD and the terminating TD.
