Abstract

A communication node processes a call supported over a voice coded channel in a wireless communication network. The node tentatively designates the call as a voice call as soon as the call is initiated. While the call is designated as a voice call, the node limits processing of the call as a text telephony call to passively monitoring for one or more partial or complete text characters in the call. Responsive to detecting one or more partial or complete text characters in the call via this passive monitoring, the node designates the call as a text telephony call. While the call is designated as a text telephony call, the node fully processes the call as a text telephony call by passively detecting one or more complete text characters in the call, and conditioning and de-conditioning signals of the call for reliable transmission and reception over the voice coded channel.
