The collect digits command collects the touchtone digits entered by a Call Prompting user. The command allows the system to collect up to 24 digits from a touchtone phone. The first 16 digits are collected immediately, while the remaining digits are stored as dial-ahead digits.
Call Prompting offers some flexibility when entering digits. The caller can:
Delete the incorrect digit string.
Enter a variable-length digit string.
Enter the dial-ahead digits.
