I've been asked about equipment to use for training young grade school children on using a telephone to call 911. My contact at the police dept. and I understand there are lots of cell phones being used in these situations, but they do want to set up some training for good old fashioned land lines.

I looked at the Viking DLE-300. It has a 911 Training mode. Is there anything else I should be looking at?

Thanks for your input.
