摘要： A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.

摘要： A network interface device may include an I/O unit configured to receive data packets from a packet network. A processing unit may be in communication with the I/O unit and be configured to identify data packets including data representative of DTMF signals, convert the data in the data packets into analog DTMF tone signals, and determine if power of the analog DTMF tone signals is below a threshold value. A digital to analog converter may be in communication with the processing unit and be configured to generate the analog DTMF tone signals based on the data in the data packets. A DTMF amplifier may be in communication with the processing unit and the digital to analog converter, where the processing unit may cause the DTMF amplifier to amplify the power of the analog DTMF tone signals in response to determining that the power of the analog DTMF tone signals are below the threshold value.

摘要： A system and method for providing location information to a public safety answering point may include registering network access points with a gateway. The registration may include address location of each network access point to enable the gateway to look-up and communicate the address location of a registered network access point during an emergency 911 call. The network access points may be WiFi access points. The network access point address location information may be communicated using a type II caller ID data packets after the public safety answering point goes off-hook. By communicating both the access point address information and GPS location information, PSAPs that are configured as E911 Phase I and E911 Phase II may display address information of an emergency 911 caller.
