NO.47 How does Cisco Unified Communications Manager perform a digit analysis on-hook versus off-hook for an outbound call from a Cisco IP phone that is registered to Cisco Unified CM?

On-hook, Unified CM performs a digit-by-digit analysis, off-hook, Unified GM considers all digits were dialed and does not wait for additional digits.

On-hook, Unified CM considers all digits were dialed and does not wait for additional digits, off-hook, Unified CM performs a digit-by-digit analysis.

On-hook, by pressing the digits and entering “#” to process the call, Unified CM performs a digit-by-digit analysis; off-hook. Unified CM analyzes all digits as a string.

On-hook, no digit analysis is performed, off-hook. Unified CM requires the “#* to start the digit analysis.
