Explanation
When a user on an SCCP (Skinny Client Control Protocol) phone goes off-hook and begins dialing, CUCM uses digit-by-digit analysis. With SCCP, each digit is transmitted to CUCM individually as it is pressed, and CUCM analyzes the digit string incrementally after each keypress against its dial plan. This allows CUCM to apply interdigit timeout and match the pattern as soon as a unique match is found (using the '#' key to force completion). In contrast, SIP phones typically use en bloc dialing (all digits sent at once) or KPML (Key Press Markup Language) for digit-by-digit reporting. SIP dial rules apply to SIP endpoints, not SCCP.
