Principles for Text over IP (ToIP)

• Text communication needs to be smooth and accurate, with low latency

  • Benchmark on voice quality, including during disaster

• Standardize on ITU T.140 as presentation protocol

• Common interchange host environment = SIP, RFC 4103

• All text conversation products to provide interoperability with the common interchange host environment (by rule if needed)

• Interoperability with legacy TTY as a migration path
