Abstract

Techniques for dynamically adjusting volume during a call are provided. A gateway (102) is provided that allows a call between a first device (104) and a second device (106). The call may be routed through a first network (110) and a second network (108). The first network may be PSTN network and the second network may be a VOIP network. An indication may be received at the gateway that indicates a call characteristic should be adjusted for the call. For example, the indication may indicate the volume or echo should be adjusted. The gateway may then adjust the volume or eliminate echo during the call based on the indication. The adjustment is affected during the call at the first device and the second device. For example, the gateway may dynamically adjust the gain for the call resulting in a change in the call characteristic.
