STEP 4 Configure the Internet Connection Type. Choose one of the following:
• Dynamic Host Configuration Protocol (DHCP): Configure the phone to
receive an IP address from the network DHCP. Cisco IP phones typically
operate in a network where a DHCP server assigns the device its IP
address. Because IP addresses are a limited resource, the DHCP server
periodically renews the device lease on the IP address. If a phone loses its
IP address for any reason, or if some other device on the network is
assigned its IP address, the communication between the SIP proxy and the
phone is either severed or degraded. Whenever an expected SIP response
is not received within a programmable amount of time after the
corresponding SIP command is sent, the
DHCP Timeout on Renewal
feature
causes the device to request a renewal of its IP address. If the DHCP server
returns the IP address that it originally assigned to the phone, the DHCP
assignment is presumed to be operating correctly. Otherwise, the phone
resets to try to fix the issue.
• Static IP—Configure a static IP address for the phone.
• PPPoE—Point-to-Point Protocol over Ethernet (PPPoE) relies on two widely
accepted standards: PPP and Ethernet. PPPoE is a specification for
connecting users on an Ethernet to the Internet through a common
broadband medium, such as a single DSL line, wireless device, or cable
modem. All users on an Ethernet share a common connection, so the
Ethernet principles supporting multiple users in a LAN combine with the
principles of PPP, which apply to serial connections.
