Adding a 6.2.2.7: Reviewing of received RTT requirement (from clause 13.4.8 of TR 103 708)
Proposal to add:
6.2.2.7 Reviewing of received RTT
Where ICT has RTT presentation capabilities, the ICT shall provide the ability to review previously received RTT input for the current or latest call.
NOTE 1: When the presentation is in a position for presenting earlier communicated text, the local user usually prefers that the reading position is only changed by local user action and not by arrival of new text, while when the presentation is positioned to present latest text, then arrival or transmission of new text is usually preferred to be automatically presented.
NOTE 2: Ideally, the ability to review the last call will last for at least 24 hours.
The results of these proposed changes can be previewed in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
