DNS server) for the IP phone can be statically configured by an administrator.
Stateless Address Autoconfiguration (SLAAC)/ ICMPv6: SLAAC is one of the most

convenient methods to assign IP addresses to IPv6 nodes. SLAAC requires no
manual configuration of the IP phone, minimal (if any) configuration of routers, and
no additional servers. To use IPv6 SLAAC, the IP phone must be connected to a
network with at least one IPv6 router connected. This router is configured by the
network administrator and sends out Router Advertisement announcements onto
the link. These announcements can allow the on-link connected IP phone to
configure itself with IPv6 address, as specified in RFC 4862.
Stateful DHCPv6: The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has

been standardized by the IETF through RFC 3315. DHCPv6 enables DHCP servers to
pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It
offers the capability of automatic allocation of reusable network addresses and
additional configuration flexibility. This protocol is a stateful counterpart to ―IPv6
Stateless Address Autoconfiguration‖
concurrently with the latter to obtain configuration parameters.

How the IP phone obtains the IPv6 address and network
settings?
You have to manually configure the static IPv6 address
and other network settings.
The IP phone can obtain the IPv6 address via SLAAC, but
the other network settings must be configured manually.
The IP phone can obtain the IPv6 address and the other
network settings via DHCPv6.
The IP phone can obtain the IPv6 address via SLAAC and
obtain other network settings via DHCPv6.
