DNS
Support for IPv6 naturally allows the snom m9 to perform AAAA queries for IPv6 address lookups. For routing
packets to IPv6 destinations, snom m9 uses its local IPv6 interface, if available.
SIP
Depending on the type of address returned (IPv4 or IPv6) for a SIP server, the snom m9 automatically selects
the corresponding IP interface for registration. SIP packet addresses and headers are also automatically sub-
stituted with the appropriate IP interface. Following is a REGISTER sample:
