The system and method of the present invention completes at least two calls originating from terminal equipment located at a premises and connected by a point-of-attachment having a single phone number to a public switched telephone network where a dial tone is provided to the premises. Multiple calls are now allowed with an analog interface to the public switched telephone network. At least two calls and control channel are combined into a modulated analog signal having a separate channel for each call and transmitted through a modulation/demodulation device as a modulated analog signal to the public switched telephone network. The modulated analog signal is split into respective calls and control channel. Each call is forwarded to a respective remote device based on the identity information and auxiliary information received through the control channel.
