Claim of US Patent No. 9,112,880

1. A method for establishing a VoIP over a cloud-based network (iVoCS), said method comprising the steps of
establishing communication between an ingress iVoCs endpoint, an engress iVoCS endpoint, an ingress edge proxy server and
an egress edge proxy server,

the ingress edge proxy server locates a target proxy server,
the ingress edge proxy server locates the egress edge proxy server by way of the target proxy server,
the ingress edge proxy server and the egress edge proxy server identify most feasible resources for one or more requested
sessions and finalize a resource allocation,

the ingress edge proxy server and the egress edge proxy server identify and assign one or more resources in a middle cloud,
and

the ingress edge proxy server and the egress edge proxy server communicate resource information on the resource allocation,
the resources in the middle cloud, or both the resource allocation and the resources in the middle cloud, to the ingress iVoCS
endpoint and the egress iVoCS endpoint.
