IP Protocol
MiVoice MX-ONE 7.0 and later releases supports IPv4 or IPv4/IPv6 in dual mode.
Please note that when MX-ONE is configured with dual mode, the communication between the Service Node and Database nodes is done in IPV6 only. So, it is important to make the correct IP Protocol choice before setup the system.
The figure below shows how the different MX-ONE components interwork with IPv4-IPv6.
