12. An apparatus for coordinating text messages from a plurality of operator devices to determine a text message to send to an emergency caller device, the apparatus comprising: a processing device adapted to establish an emergency text messaging session, which establishes a media path between the apparatus and the emergency caller device, and adapted to establish a call leg to the session for each of a first operator device and a second operator device; and an interface adapted to receive a first text message from the first operator device and a second text message from the second operator device and provide real-time messaging between the first and the second operators such that each operator device sees contents of the other operator's text messages being typed in real time before any text message is sent to the emergency caller device; wherein the processing device is further adapted to apply a set of rules to the first and the second text messages to determine at least one text message to send to the emergency caller device; and wherein the interface is further adapted to send the at least one text message to the emergency caller device, wherein each text message sent to the emergency caller device is associated with a same identifier; wherein the set of rules comprises at least one of: a rule to send a first text message from a first responding device, and provide an indication to a second responding device that a second text message was not sent; a rule to send a second text message from the second responding device when the second responding device has assigned an override-drop status to the second text message; a rule to send either the first or the second text message based on a role of the first or the second responding device; or a rule to send the first text message delay sending the second text message by a delay time interval.
12. An apparatus for coordinating text messages from a plurality of operator devices to determine a text message to send to an emergency caller device, the apparatus comprising: a processing device adapted to establish an emergency text messaging session, which establishes a media path between the apparatus and the emergency caller device, and adapted to establish a call leg to the session for each of a first operator device and a second operator device; and an interface adapted to receive a first text message from the first operator device and a second text message from the second operator device and provide real-time messaging between the first and the second operators such that each operator device sees contents of the other operator's text messages being typed in real time before any text message is sent to the emergency caller device; wherein the processing device is further adapted to apply a set of rules to the first and the second text messages to determine at least one text message to send to the emergency caller device; and wherein the interface is further adapted to send the at least one text message to the emergency caller device, wherein each text message sent to the emergency caller device is associated with a same identifier; wherein the set of rules comprises at least one of: a rule to send a first text message from a first responding device, and provide an indication to a second responding device that a second text message was not sent; a rule to send a second text message from the second responding device when the second responding device has assigned an override-drop status to the second text message; a rule to send either the first or the second text message based on a role of the first or the second responding device; or a rule to send the first text message delay sending the second text message by a delay time interval. 13. The apparatus of claim 12 , wherein content of the first and second text messages is received into the interface in real time as the content is typed into the first and second operator devices, wherein the interface is further adapted to: send the content of the first text message in real time to the second operator device as the content of the first text message is typed into the first operator device; and send the content of the second text message in real time to the first operator device as the content of the second text message is typed into the second operator device.
