Question 9

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?
A) On-hook, Unified CM performs a digit-by-digit analysis; off-hook, Unified CM considers all digits were dialed and does not wait for additional digits.
B) 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.
C) 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.
D) On-hook, no digit analysis is performed; off-hook, Unified CM requires the "#* to start the digit analysis.

Accepted Answer

On-hook, the user can press digits and then "#" to indicate the end of dialing, allowing Unified CM to perform digit-by-digit analysis. Off-hook, Unified CM analyzes the entire string of digits once the user finishes dialing.
