Freeswitch Develop

We are looking for an experienced programmer(s) to develop and deploy a redundant, scalable FreeSWITCH system to be used to provide VOIP service to our businesses. The system must support real-time communications between FreeSWITCH servers in multiple locations so that a failure of one server, or one data center has the least possible impact on active calls.

Our goal is to have servers running in two separate physical data centers on Day 1 and grow that number over time. The system must support the easy addition of additional servers to support growth and improve call quality.
