Adding a 6.2.9: RTT activation (from clause 13.4.11 of TR 103 708)

Proposal to add:

6.2.9 RTT activation

Where ICT has RTT capabilities,
it shall be possible to activate RTT both when initiating and answering a call and to activate RTT during the call by any RTT-enabled endpoint.

NOTE: The activation could be by a user, an automatic procedure in a user terminal, a non-human process, or a setting in a conference call.

The results of these proposed changes can be previewed in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
