Question :-

What are the two benefits of using SIP dial rules on an IP phone? (Choose two)
The phone can initiate dialing without sending any signaling messages to Cisco Unified Communications Manager.
The phone can detect invalid numbers and play a reorder tone without sending any signaling messages to Cisco Unified Communications Manager.
If dialed digits match an entry of a SIP dial rule, the dialed string is sent in a single SIP 200 OK message to Cisco Unified Communications Manager.
If Cisco Unified Communications Manager requires more digits, KPML can be used to send the remaining digits from the SIP phone to Cisco Unified Communications Manager one-by-one.
If Cisco Unified Communications Manager requires more digits, another en bloc message is used to send the remaining digits from the SIP.
