Media/SDP

OpenStage phones support IPv4/IPv6 media address negotiation in SDP using ANAT (Alterna-
tive Network Address Types). ANAT allows for for the expression of alternative network ad-
dresses (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.
If SRTP is enabled, ANAT interworking is only possible if SDES is configured as the
>
key exchange protocol for SRTP (see Section 3.4.1.1, "General Configuration").
Media IP mode defines which IP version is to be used for voice transmission. With "IPv4", only
IPv4 is used; with "IPv6", only IPv6 is used; with "IPv4_IPv6", both IPv4 and IPv6 can be used,
but IPv4 is preferred; with "IPv6_IPv4", both IPv6 and IPv4 can be used, but IPv6 is preferred.
