1. A system for establishing text communication sessions between wireless mobile devices and emergency call centers, the system comprising:
- a non-transitory computer readable storage medium having computer readable instructions embodied thereon; and
one or more hardware processors configured by the computer readable instructions to;
receive session invitation messages that are used to establish communication sessions between wireless mobile devices and an emergency call center, the session invitation messages specifying a media type of incoming emergency communications paced to the emergency call center from the wireless mobile devices;
responsive to reception of a first session invitation message used to establish a first session between a first wireless mobile device and the emergency call center, in which the first session invitation message specifies that an incoming emergency communication for the first session is a textual media type, effectuate a change in the first session invitation message to specify that the incoming emergency communication for the first session is an audio media type;
effectuate transmission of the first session invitation message to the emergency call center, and receive a first response message from the emergency call center, the first response message specifying the audio media type as an accepted media type for the incoming emergency communication received at the emergency call center during the first session; and
effectuate a change in the first response message such that the first response message specifies the textual media type as the accepted media type for the incoming emergency communication received at the emergency call center during the first session, and effectuate transmission of the first response message to the first wireless mobile devices, wherein the transmission on the first response message facilitates establishing the first session, wherein effectuating the change in the first session invitation message comprises one or more of replacing, substituting, and/or redefining information associated with an m-line identifier or a-line information with replacement syntax and/or information related to a media type, the substituting including substituting a description in the first session invitation message that indicates the textual media type with a new description that indicates the audio media type, wherein the a-line shows path information and an accepted media type.

10. A method of establishing text communication sessions between wireless mobile devices and emergency call centers, the method being implemented in a computer system including one or more physical processors and storage media storing machine-readable instructions, the method comprising:
-
receiving session invitation messages that are used to establish communication sessions between wireless mobile devices and an emergency call center, the session invitation messages specifying a media type of incoming emergency communications placed to the emergency call center from the wireless mobile devices; responsive to reception of a first session invitation message used to establish a first session between a first wireless mobile device and the emergency call center, in which the first session invitation message specifies that an incoming emergency communication for the first session is of a textual media type, effectuating a change in the first session invitation message to specify that the incoming emergency communication for the first session is of an audio media type; effectuating transmission the first session invitation message to the emergency call center, and receiving a first response message from the emergency call center, the first response message specifying the audio media type as an accepted media type for the incoming emergency communication received at the emergency call center during the first session; and effectuating a change in the first response message such that the first response message specifies the textual media type as the accepted media type for the incoming emergency communication received at the emergency call center during the first session, and effectuating transmission of the first response message to the first wireless mobile devices, wherein the transmission of the first response message facilitates establishing the first session, wherein effectuating the change in the first session invitation message comprises one or more of replacing, substituting, and/or redefining information associated with an m-line identifier or a-line information with replacement syntax and/or information related to a media type, the substituting including substituting a description in the first session invitation message that indicates the textual media type with a new description that indicates the audio media type, wherein the a-line shows path information and an accepted media type. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
