Definitions
There are 3 types of devices:
• Pure IPv4 devices: Pure IPv4 devices can be configured only with IPv4 addressing.
• Pure IPv6 devices: Pure IPv6 devices can be configured only with IPv6 addressing.
• Dual stack devices: Dual stack devices can be configured as a pure IPv4 device, a pure IPv6 device or a
mixed mode device which have both an IPv4 and an IPv6 address.
An IP network can be divided into 3 subnetworks:
• A pure IPv6 subnetwork is only supporting IPv6 addressing devices. Pure IPv6 and dual stack devices
can be placed in this network.
• A pure IPv4 subnetwork is only supporting IPv4 addressing devices. Pure IPv4 and dual stack devices
can be placed in this network.
• A mixed subnetwork: supporting all type of devices. Pure IPv4, pure IPv6 and dual stack devices can
be placed in this network.

Deskphones
The following IP Premium desk phones running on NOE protocol are dual stack devices:
– They support both IPv4 or IPv6 addressing.
– They can be placed in an IPv4, an IPv6 or a mixed IPv4/IPv6 subnetwork.
When running in IPv6, there is no DHCP survivability, and the embedded VPN client is not available
(*) Hybrid ALE-20h and ALE-30h in IP mode
All other ALE IP desk phones running on NOE protocol or on SIP protocol are pure IPv4 devices:
– They support IPv4 addressing.
– They can be placed in an IPv4 or a mixed IPv4/IPv6 subnetwork.

– The ABC-A Communication handler (4059 module used for signaling purpose) can use IPv6
addresses. It supports both IPv4 or IPv6 addressing and can be placed in an IPv4, an IPv6 or
a mixed IPv4/IPv6 subnetwork.
– When 4059 EE is associated to a dual stack Premium deskphone, the 4059 EE is full dual
stack for voice and signaling, if the 4059 EE is associated to another deskphone, voice is
only IPv4.

OXE call server is pure IPv4
– It support IPv4 addressing.
– It can be placed in an IPv4 or a mixed IPv4/IPv6 subnetwork.
Support of IPv6 requires that OXE call servers (main, standby) and PCS are virtualized.
IP Premium SSM and MSM security modules are dual stack as of OXE release 12.0
– They support both IPv4 or IPv6 addressing.
– They can be placed in an IPv4, an IPv6 or a mixed IPv4/IPv6 subnetwork.
As of October 2020, the IP Premium Security solution is phased out. It will be supported
according to the ALE release policy.

OST64
OXE Call server is pure IPv4. It can operate in IPv6 via the OST64 server.
OST64 - OXE Signaling Translator for interfacing IPv6 & IPv4 NOE signaling
– A virtualized software component co-localized with other VMs (e.g. OXE-V) acting as a proxy, that
translates the IPv4 signaling messages from CS, to IPv6 signaling messages towards IPv6 devices and
vice versa.
– Supports only NOE & IP Link protocols (SIP & H323 are not translated)
– There is one OST64 instance per OXE Call server or PCS
– OST64 is a dual stack device and must be installed in a mixed IPv4/IPv6 network.

RTP Proxy
Compression resources
RTP proxy converts IPv4 media streams from pure IPv4 devices to IPv6 media streams towards
pure IPv6 devices and vice versa.
It uses compression resources of the IP Media Gateway. One RTP Proxy feature requires 2
compressions resources. The IP Media Gateway can be configured to dedicate all of its
compression resources, or only a part of them to work as RTP Proxy.
Example: a GD3/4 with an ARMADA daughter board has 60 compression resources.

RTP Proxy Sizing
General principles
Sizing of RTP Proxy depends on the customer topology. It depends on the RTP flows between the
IPv6 and the IPv4 area.
The following recommendations must be followed-up:
It is recommended to migrate existing Media Gateway to the dual stack IPv4/IPv6 version:
GA3/GD3 or GA4/GD4, INTIP3A/INTIP3B
If there are IPv4 and IPv6 devices that can do external calls, the PSTN access must be on Media
Gateway running in a mixed IPv6/IPv4 mode.
The design must minimize the mix of IPv4 and IPv6 devices.
It is strongly recommended that you contact the central presales team to check the RTP proxy
configuration.

DHCP and TFTP servers
IPv6 compatible IP deskphones support both statefull (DHCPv6) and stateless (SLAAC) auto-
configuration
DHCP server
–In IPv4, the DHCP server can be either external, or embedded in the call server.
–In IPv6, the DHCP server must be external (Call server don’t support IPv6)
TFTP server
–IPv4 operation : IPv4 TFTP Server is provided by OXE Call server
• OXE Call server is IPv4 TFTP server for IPv4 devices (IP Touch, IPMG GD2)
• OXE Call server is IPv4 TFTP server for OST64
–IPv6 operation : IPv6 TFTP Server is provided by OST64
• OST64 is IPv6 TFTP server for IPv6 devices and IPv6 IPMG (GD3, GA3, GD4, GA4)

ACTIS
Configure IPv6 and OST 64
Check IPv6 and configure the number of OST64:
There is one OST64 instance per OXE Call server
or PCS. (multiply by 2 in case of OST redundancy)
ACTIS configures one SUSE Linux license per OST64. Price of this support is fully integrated in the SPS as of Actis 23.1
Additional IPMG(s) for RTP Proxy function depends on RTP traffics between IPv6 zone & IPv4 zone
