• Domain Name System (DNS)
DNS is used in the Internet for translating names of network nodes into
addresses. SIP uses DNS to resolve the host names of end points to IP
addresses.
Dynamic Host Control Protocol (DHCP)
•
DHCP is used to dynamically allocate and assign IP addresses. DHCP allows
you to move network devices from one subnet to another without
administrative attention. If using DHCP, you can connect Cisco SIP IP phones
to the network and become operational without having to manually assign an
IP address and additional network parameters.
The Cisco SIP IP phone complies with the DHCP specifications documented
in RFC 2131. By default, Cisco SIP IP phones are DHCP-enabled.
