In computer telephony an automatic dialler (shortened to an autodialler or more simply in context just a dialler, and also known as an outbound dialler) is a computer system that makes outgoing calls from a call centre to customers from call agents based upon a loaded list of contacts.

The calling convention of a given program's language may differ from the calling convention of the underlying platform, OS, or of some library being linked to. 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 ...
The calling convention of the System V AMD64 ABI is followed on Solaris, Linux, FreeBSD, macOS, [26] and is the de facto standard among Unix and Unix-like operating systems. The OpenVMS Calling Standard on x86-64 is based on the System V ABI with some extensions needed for backwards compatibility. [ 27 ]
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
The cost of making a telephone call via callback consists of two parts, as the caller is effectively paying for an outbound and inbound call at the same time. For example, if a customer from Spain is calling a phone number in Australia, and it costs 8 cents per minute to phone Spain from the US (the callback, which is an incoming call) and 20 ...
Depending on the language, operating system, and machine environment, a call stack may serve additional purposes, including, for example: Local data storage A subroutine frequently needs memory space for storing the values of local variables, the variables that are known only within the active subroutine and do not retain values after it ...
