1. A method of managing call information at a Public Safety Answering Point (PSAP), the PSAP in communication with a Automatic Location Identification ALI database, comprising:
- receiving an analog voice call from a caller,converting the analog voice call to a digital voice call,collecting information from the caller, wherein collecting information about the caller comprises receiving, from the ALI database, geographical coordinates when the caller is a wireless caller,sending a handshake message across a network to determine if other PSAPs are connected to the network, wherein the PSAP recognizes when the other PSAPs are added to, moved, or deleted from the network;
when other PSAPs are connected to the network, determining whether to transfer the caller to a subsequent PSAP if certain conditions are satisfied, wherein determining whether to transfer the caller to the subsequent PSAP comprises determining if the PSAP is compatible with a recognized transmission schema by querying the subsequent PSAP with an acknowledgment message, requesting acknowledgment from the subsequent PSAP of the recognized transmission schema, andwhen the subsequent PSAP acknowledges the recognized transmission schema, transferring the caller, the digital voice call, and the collected information to the subsequent PSAP if the certain conditions are satisfied.

Abstract
Methods and systems are provided for managing call sessions on public and private networks. The methods and systems operate to receive and send voice over internet protocol (VoIP) communications using a network, such as an IP network. The methods and systems also operate to receive and send emergency information over IP and other data networks. Based on certain criteria, the methods and systems determine whether to transfer a VoIP communication and/or emergency information to another entity associated with the IP network.

10. A method of managing call information comprising:
-
receiving a VoIP communication from a first entity in communication with an IP network, receiving emergency information from the first entity via the IP network, wherein receiving emergency information comprises collecting information from a caller, wherein collecting information about the caller comprises receiving, from an Automatic Location Identification (ALI) database, geographical coordinates when the caller is a wireless caller, and determining whether to transfer the VoIP communication or the emergency information to a subsequent entity associated with the IP network, wherein determining whether to transfer the caller to the subsequent entity comprises determining if a PSAP is compatible with VoIP equipment, wherein determining whether to transfer the VoIP communication or the emergency information comprises; sending a handshake message across a network to determine if other PSAPs are connected to the network, wherein the PSAP recognizes when the other PSAPs are added to, moved, or deleted from the network, and determining if the PSAP is compatible with a recognized transmission schema by querying the subsequent PSAP with an acknowledgment message and requesting acknowledgment from the subsequent PSAP of the recognized transmission schema. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for managing a call session in an emergency response communication system, the system comprising:
-
a controller for receiving data corresponding to Automatic Number Identification (ANI) or Automatic Location Identification (ALI), a communication device for communicating with a caller reporting an emergency, an interface for communicating with a network, the interface including operability to transmit and/or receive analog and/or digital voice communications via the network, the interface further operable to transmit and/or receive emergency related data using voice over internet protocol (VoIP) communications, the system for; sending a handshake message across a network to determine if other PSAPs are connected to the network, wherein the PSAP recognizes when the other PSAPs are added to, moved, or deleted from the network, and when other PSAPs are connected to the network, determining whether to transfer the analog or digital voice communications and/or the emergency data to another entity associated with the network, based at least in part on whether the entity is currently in communication with the network and is a designated responder, wherein determining whether to transfer the analog and/or digital voice communications and/or the emergency data to another entity associated with the network comprises determining if a PSAP is compatible with VoIP equipment by querying the subsequent PSAP with an acknowledgment message and requesting acknowledgment from the subsequent PSAP of the recognized transmission schema. - View Dependent Claims (19, 20)
