Internet Protocol (IP) audio conferencing bridging provisioning/configuration systems receive a service order request associated with a customer, where the service order request requests enrollment of the customer in a Virtual Private Network (VPN) bridging network service for IP Audio Conferencing. The provisioning/configuration systems orchestrate, based on the service order request, configuration of multiple network nodes in a network that provides the VPN bridging network service for IP Audio Conferencing to the customer to enable IP audio conferencing calls to be made from the customer via the network.
