When a user dials a telephone number from a Type A SIP phone, how are the digits analyzed by Cisco Unified Communications Manager if no SIP dial rules are configured?
A. If there are no dial rules present and the user uses the Dial softkey the digits are sent to the Cisco Unified Communications Manager digit-by-digit.
B. With a Type A SIP phone the digits are only sent en bloc.
C. When no dial rules are present, digits are sent to the Cisco Unified Communications Manager digit-by-digit.
D. When no dial rules are present, digits are sent to the Cisco Unified Communications Manager en bloc.
Type A Cisco IP Phones using SIP firmware without SIP dial rules do not deliver a dial tone to the calling party when the calling party goes off-hook with the handset or speaker phone. All digits are sent to CUCM enbloc after the user completes the dialing and press the Dial softkey.
