On-Premises Call Control

For SIP integrations with Cisco Unified Communications Manager, when Cisco Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, how should the addressing mode be configured in Cisco Unity Connection?

  • A Set up is not required.
  • B Set up for each group to use IPv4 and IPv6.
  • C Set up media ports for each port group to use IPv4.
  • D Set up IPv4 and IPv6 in Cisco Unified CM.
Explanation

For Cisco Unified Communications Manager SIP integrations, a Unity Connection system listening on both IPv4 and IPv6 supports selecting the call-control signaling addressing mode for each port group as either IPv4 or IPv6; SIP media addressing can likewise be configured per port group.
