A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network. The system may include one or more conference servers for combining IP packet streams in a conference call into a combined IP packet stream, such that the combined IP packet stream utilizes no more bandwidth than each of the original IP packet streams. This allows the traffic volume coming from, and arriving at, each party to a conference call to remain essentially the same no matter how many parties are connected to the conference call. A plurality of the conference servers may be configured to interwork with each other so as to allow for a much larger conference call.
