To allocate Audio Conference Servers (CS) [1] for virtual conferencing over IP, we leverage Session Ini-tiation Protocol (SIP) for signaling. We address here the problem of facilitating seamless conference amongst participants using CSs. This demands a proper allocation of CSs to clients to maximize the number of participants served and at a reduced cost. Seeking a more realistic approach, we avoid over-simplifying assumptions; hence the problem becomes relatively harder. We present three heuristic algo-rithms for these NP-hard problems and bring about the effectiveness of their performance
