A method and apparatus for bundling packets together for transmission in a Voice over IP communications network based on packet location within a talk spurt. Illustratively, all frames other than the first and last frames of a talk spurt may be advantageously bundled up to a predetermined maximum bundle size. This results from the recognition that the first and last packets of the talk spurt are the packets that will most directly affect the conversational delay. Therefore, other packets can be advantageously considered to be "non-critical" (with respect to conversational delay), and thus, may be bundled together with one or more other packets. In this manner, bandwidth may be advantageously reduced without negatively impacting the perceived conversational delay.
