For VoIP calls over a communication system in which a remote terminal is requesting to a hub-gateway, bandwidth may be allocated according to a dynamic technique based on the packet rate between an access device and the remote terminal by sending a bandwidth request message from the access device to the hub-gateway or to the remote terminal containing information on bandwidth allocation requirements for a given set of VoIP calls. The hub-gateway or the remote terminal identifies the received messaged information and analyzes the information on bandwidth allocation requirements contained in the messaged information. In addition, the hub-gateway, or the remote terminal, upon necessity, sends a request to the hub-gateway for bandwidth to be allocated in accordance with the analyzed information on bandwidth allocation requirements.
