Dynamic call characteristic control on a per call basis

A method for dynamically adjusting gain or impedance during a call using a gateway, the method comprising:

• allowing the call between a first device and a second device at a gateway, the call being routed through a PSTN network and VOIP network, the first device including a PSTN device and the second device including a VOIP device;
• receiving an indication at an adjuster of the gateway that a call characteristic should be adjusted for the call;
• and
• adjusting gain or impedance for the call at the gateway based on the indication, the adjustment being effected at the first device and the second device during the call.

A system for dynamically adjusting a characteristic for a communication, the method comprising:

• a first device configured to communicate using a first network;
• a second device configured to communicate using a second network;
• and
• a gateway configured to allow a communication between the first device and the second device, the communication being routed through a first network and the second network, the first network being different from the second network, the gateway comprising:
• an adjuster configured to:
• receive an indication at an adjuster of the gateway that a characteristic of the communication should be adjusted for the call;
• and
• adjust the characteristic during the communication based on the indication, the adjustment being effected at the first device and the second device during the communication.

An information storage medium having a plurality of instructions for dynamically adjusting a characteristic for a communication using a gateway, the steps including:

• allowing a communication between a first device and a second device at the gateway, the communication being routed through a first network and second network, the first network being different from the second network;
• receiving an indication at an adjuster of the gateway that a characteristic should be adjusted for the communication;
• and
• adjusting the characteristic at the gateway during the communication based on the indication, the adjustment being effected at the first device and the second device during the communication.
