Well, push to talk makes very much sense whereever you have to reach a
group of recipients at once. Push to talk over cellular is quite popular
among US law enforcement agencies e.g.
When I was still living in Germany, I was heavily utilizing PTT to
coordinate my service team. It's just practical. One talks, everybody
listens. Radio simpleness but GSM reliabilty and quality.

Besides that was the original reason for me looking for the Nokia
autoanswer feature. After PTT didn't work with *, I thought of simply
calling a list of phones with autoanswer and throwing them into a
meetme. As I do with SCCP phones here now.

Which would reach how far? 500m? Surely not from Helsinki to Oulu or
even internationally...
