scope:

Total Conversation, as defined in ITU-T Recommendation F.703 [i.3], is a combination of three media in a conversational call: video, real-time text and audio. The present document describes conditions for using Total Conversation for emergency services and makes access of emergency services possible to people with disabilities. The present document addresses the impact on PSAP organisations and potential impact on overall emergency services organisations. It also addresses functional requirements regarding the interface to the PSAP, the connection to external supporting services, the transferring and sharing of the call between call handling organisations, the call logging and call recording at the PSAP, call-back aspects and specific call routing and location information provision aspects for these calls.

The service described here is one solution for accessible emergency services intended to fulfil requirements in the EU Universal Service Directive. Other solutions may be possible and can be added.

Due consideration is taken of related standardisation (e.g. 3GPP) and work in other bodies (e.g. EGEA).
