Systems and methods for routing internet protocol telephony communications
View Patent ↗When IP telephony devices that make use of an Internet protocol (IP) based private branch exchange (PBX) service provider resister with the PBX service provider, they furnish local area network address information that indicates how the telephony devices can be reached directly on the local area network to which they are connected. This information is provided to other telephony devices within the same business or organization. As a result, the telephony devices within a business or organization can contact one another directly to setup and conduct telephony communications over a local area network, without the need for such telephony communications to pass over a public data network, or though assets of the IP based PBX service provider.
