Although, in my experience using a tonegen often results in tones  
that are not understood by a number of other systems. I'm not sure if  
this is due to audio volume issues or what, but we've had a number of  
systems that can't understand some or all digits from the tonegen.  
Sending SIP INFO messages to our Cisco to then generate them always
