In an exemplary method audible signals from participants of a conference call during the ongoing conference call are processed by a conference bridge. An incoming audible signal on a first line from a first participant is detected during the conference call with a plurality of other conference call participants coupled via corresponding other lines. The audible signal on the first line is automatically attenuated before information on the first line is summed into a common signal that is transmitted to the other conference call participants. This prevents the other participants from hearing the audible signal during the ongoing conference call.

A method in one example comprises the steps of establishing a location database for a first network that associates Internet Protocol address information for VOIP telephony devices with physical locations for the VOIP telephony devices; upon detecting registration of a VOIP telephony device through a network port of the first network, determining physical location of the VOIP telephony device by identifying physical location of the network port through which the VOIP telephony device is connected, and updating the location database; and, upon detecting IP telephony activity originating from a remote VOIP telephony device connected to the first network through a VPN gateway, determining physical location of the remote VOIP telephony device connected through the VPN gateway by identifying physical locations of network resources of a second network to which the remote VOIP telephony device is connected, and updating the location database; such that updated location information is provided to a 911 server in the event that an emergency call is originated by any VOIP telephony device or remote VOIP telephony device.

An apparatus in one example has: a public switched telephone network; an Internet Protocol network; migration portal operatively coupled to the Internet Protocol network and to the public switched telephone network; and the migration portal having an information converter, the information converter having inputs for receiving public switched telephone number related information that is utilized in the public switched telephone network, and having outputs for providing Voice Over Internet Protocol telephone number related information that is utilized in the Internet Protocol network, the Voice Over Internet Protocol telephone number related information being a function of a predetermined subset of the public switched telephone number related information.

Systems and methods are presented for providing updated VOIP terminal location information to emergency call service providers, in which RFID tags are positioned at various locations within an enterprise and coded with unique tag data. A database is provided with a mapping of RFID tag data and tag locations in the enterprise, and the VOIP phone terminals are equipped or otherwise connected with RFID tag readers. The VOIP phones read the tag data upon initiation of a 911 or other an emergency call and report the tag data to a network server that determines the VOIP phone location according to the tag data and provides the phone location to the emergency call service provider.
