Abstract
An apparatus and a method are provided for proxying communications between devices on an IP telephony network. In a preferred embodiment, an appliance comprising a network server and proxy server software includes filtering rules which can be modified to enable proxied communication between an IP phone on a first data network, such as, for example, the internet, and a call processing server located on a second data network. In another embodiment, an appliance comprises a proxy server that proxies call-processing and signaling communications between an authenticated IP phone on a first data network and a call processing server located on a second data network. In another embodiment, the appliance relays voice traffic between IP phones. In another embodiment, the proxy server software operates in a secure mode to permit encryption and decryption of voice and control communications. In another embodiment, the proxy server enables proxied communications between a call processing server and an IP phone by modifying the provisioning data exchanged between the call processing server and the IP phone.
