摘要：
A communication scheme allows two Voice Over Internet Protocol (VoIP) gateways that do not necessarily support a common set of Public Switched Telephone Network (PSTN) text terminal (TTY) modulations and which are communicating with dissimilar PSTN text terminal devices to negotiate a transition to text relay mode thus allowing those dissimilar PSTN text terminal devices to interwork with each other.
