On-Premises Call Control

How does Cisco Unified Communications Manager carry out digit analysis for an outbound call from a Cisco IP phone registered with Cisco Unified CM when dialing on-hook versus off-hook?

  • 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 ג€#* to start the digit analysis.
Explanation

On-hook dialing presents Unified CM with the completed dialed digit string, allowing it to treat dialing as finished without waiting for additional digits. Off-hook dialing sends digits incrementally, so Unified CM performs digit-by-digit analysis as each digit is entered.
