Make audio conference call with 250 or more number of people on group chat participation, mixed locally to minimize latency.
Group participants or aid workers can use the group tools in OBTalker to communicate immediately with a large group of volunteers.
In situations where all parties need to talk at once the organizer can quickly spin up a conference line.
In other situations she can broadcast a spoken message to a list of volunteer phone numbers.
