This was mentioned is the initial RTCWeb session at IETF 81 but just to make sure it has been captured and understood.

(1) Please can a separate use case be added for an Emergency Services telephony call (eg 999 in UK, 112 in EU, 911 in NA, etc). 

(2) Please can a further separate use case be added for an Emergency Services real time text (eg 18000 in UK, via TextDirect operator to ES operator for hearing impaired persons). FYI today this is a low speed in-band voice band data call on the text leg. Presumably the replacement would be some kind of Presence/Messaging replacement with assured delivery or similar.

Please note these are treated differently today in current networks and I would suggest we aim to preserve the capabilities - subject to discussion in the community, in the right WG - eg ECRIT. These are, using legacy terminology ...

A). Prioritisation in processing of Emergency Services calls above Ordinary Calls, particularly when server in overload.

B). Marking of Emergency Services calls to a specific A-/Calling Party Category to allow them to be identified downstream.

C). Release control modified to B-/Called Party Control with changed RTCWeb browser client behaviour along with indication as to "Off Hook" and "On Hook".
