Which of the following does the SIP protocol do when one VoIP caller places a call to another VoIP user?
  1. Converts the telephone number into the MAC address of the destination phone.
  2. Converts the telephone number into the IP address of the destination phone.
  3. Converts the telephone number into the IP address of the source phone.
  4. Converts the telephone number into the MAC address of the destination phone.
Explanation
Answer - B - SIP converts the telephone number into the IP address of the destination phone.

Key Takeaway: SIP allows one VoIP caller to place a call to another VoIP user. When a caller dials the phone number of a VoIP-based user, SIP converts the telephone number into the IP address of the destination phone. It then sends an invitation to the destination address. This causes the phone to ring.
