OpenScape Desk Phones support IPv4/IPv6 media address negotiation in SDP
using ANAT (Alternative Network Address Types). ANAT allows for for the
expression of alternative network addresses (e. g., different IP versions) for a
particular media stream.
When Media negotation is set to "ANAT", ANAT is supported; the phone will re-
register with the SIP server and advertise ANAT support in the SIP header. When
set to "Single IP", ANAT support is disabled.
INFO: If SRTP is enabled, ANAT interworking is only possible if
SDES is configured as the key exchange protocol for SRTP (see
Security - General Configuration).
