ABSTRACT:
Methods and systems of routing calls over a network are described herein. A latency measurement is performed for at least a plurality of portions of a plurality of network paths and storing latency measurement information in computer readable memory. A dropped packet measurement is performed for at least portions of the plurality of network paths and storing dropped packet measurement information in computer readable memory. A call origination request is received. A network routing path is selected from the plurality of network paths, the network paths including a call manager, based at least in part on the latency measurement information and the dropped packet measurement information. A proxy system associated with a SIP provider is informed of the call. The call manager in the selected network path generates the call.
