Sipgate uses this code if an account does not have sufficient funds to start a call. [13] Shopify uses this code when the store has not paid their fees and is temporarily disabled. [14] Stripe uses this code for failed payments where parameters were correct, for example blocked fraudulent payments. [15] 403 Forbidden
An intermediary machine or process rejected the call attempt. [25] This contrasts with the 607 (Unwanted) SIP response code in which a human, the called party, rejected the call. The intermediary rejecting the call should include a Call-Info header with "purpose" value "jwscard", with the jCard [26] with contact details. The calling party can ...
On many computer operating systems, a computer process terminates its execution by making an exit system call. More generally, an exit in a multithreading environment means that a thread of execution has stopped running. For resource management, the operating system reclaims resources (memory, files, etc.) that were used by the process.
Exit status. In computing, the exit status (also exit code or exit value) of a terminated process is an integer number that is made available to its parent process (or caller). In DOS, this may be referred to as an errorlevel. When computer programs are executed, the operating system creates an abstract entity called a process in which the book ...
Special information tone. In telephony, a special information tone (SIT) is an in-band international standard call progress tone consisting of three rising tones indicating a call has failed. It usually precedes a recorded announcement describing the problem. [1][2]
System call. 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.
List of FTP server return codes. FTP server return codes always have three digits, and each digit has a special meaning. [1] The first digit denotes whether the response is good, bad or incomplete: Range. Purpose. 1xx. Positive Preliminary reply. The requested action is being initiated; expect another reply before proceeding with a new command.
Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
