Systems and methods are disclosed for transporting multimedia protocol traffic over a proxy server using a commonly-used proxy protocol. Multimedia protocol traffic from a first endpoint is received and then converted. The converted data is then transmitted using a commonly-used protocol across a network. The traffic is received and reconverted to the original multimedia protocol. The reconverted data is then transmitted to a second endpoint. By using a commonly-used protocol to transmit traffic between endpoints, proxy servers between each endpoint may be traversed without changing any of their settings.
