We have a system that allows for incoming calls from an automated system. It uses DTMF tones to transer data from the client to the server. The issue is that when we pass the DTMF tones through the Cisco switch and the cisco vg224 the tones are not regenerated correctly. The tones are distorted which causes periodic failures in the client/server communications. Does anyone know how to directly pass DTMF tones through a Cisco system without distorting the tones?
