The sequence of operations performed by a switching system from the acceptance of an incoming call through the final disposition of the call. [1] See call control for a more complete description. The series of steps and processes by which an organization automates the handling of telephone calls (usually incoming calls).
In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
Call features provide a customised experience for the caller and maximize the efficiency of inbound call handling. Call management parameters can specify how calls are distributed according to an operator's skill level in relation to a call, the time and/or date of a call, the location of the caller or through automatic routing processes.

In European networks an “R” button is used in combination with touch tone digits to select various call handling functions. For example: Call Waiting: R1 — Answers incoming call & terminates current call. R2 — Answers current call & allows the user to toggle between calls. R3 — Establishes a 3-party conference.
An automated call distribution system, commonly known as automatic call distributor or automatic call dispatcher (ACD), is a telephony device that answers and distributes incoming calls to a specific group of terminals or agents within an organization. ACDs direct calls based on parameters that may include the caller's telephone number, the ...
For example, on 32-bit Windows, operating system calls have the stdcall calling convention, whereas many C programs that run there use the cdecl calling convention. To accommodate these differences in calling convention, compilers often permit keywords that specify the calling convention for a given function.
The G-MSC for handling incoming calls; The VLR for handling requests from mobile phones to attach to the network; The SMSC for handling incoming SMSs; The voice mail system for delivering notifications to the mobile phone that a message is waiting; The AuC for authentication and ciphering and exchange of data (triplets)
Q.2931 [3] is a modified and extended variant of Q.931 for use on "B-ISDN" or ATM networks. Q.2931 fulfils a purpose within BISDN similar to that of Q.931 in ISDN. Whilst ISDN allocates bandwidth in fixed 64k increments, B-ISDN/ATM incorporates an elaborate traffic management scheme, allowing precise specification of virtual circuit traffic parameters such as peak and mean bandwidth, jitter ...
