DNS server) for the IP phone can be statically configured by an administrator.
Stateless Address Autoconfiguration (SLAAC): 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 RFC3315. 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", and can be used separately or in addition to
the stateless autoconfiguration to obtain configuration parameters.
Note
Stateful DHCPv6 address assignment method feature is only applicable to SIP-T48G IP
phones.
If the IP phone enables the SLAAC and DHCPv6 features simultaneously, the IP phone will
obtain the IP address via SLAAC and obtain other network parameters via DHCPv6.
Procedure
IPv6 can be configured using the configuration files or locally.
