Yeah, and, coming soon, emergency call. Endpoints may have to be able to have a two way call to a call center upgraded to an emergency 3 way call using a bridge at a PSAP. This means all devices, effectively, will have to support 3891.
This would occur when you call a call center that handles a wide range of help and the call center decides it needs to make the call an emergency call. It's hard to know in advance which devices may have a need to do this.
