Add 13.3.3: Callback during emergency calls (from clause 13.9.2 of TR 103 708)
Proposal to add:
13.3.3 Callback during emergency calls
Callback from the emergency services to ICT operated by a user in an emergency shall be supported with the same or greater combination of conversational media (voice, video, RTT) as the original call to emergency services.
EXAMPLE 1: An emergency services callback for a Voice+RTT call would be expected to support both Voice and RTT.
EXAMPLE 2: An emergency service callback for a Voice+RTT+Video call would be expected to support Voice, Video, and RTT.
The results of these proposed changes can be previewed in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
