This is a simplistic calculation as there are going to be some references that have nothing to do with a call. They will also sound better than transcoding from the gsm versions. Actually, the handling is so limited that if, for some reason, a FastAGI script fails during execution, Asterisk will simply disconnect the call. People are often tempted to implement all sorts of fancy functionality in the emergency services portions of their dialplans, but if a bug in one of your fancy features causes an emergency call to fail, lives could be at risk.
