We're in the process of replacing an ancient Centigram-based, but Fujitsu-labelled, voicemail system with an Asterisk solution. The system will interface with a Fujitsu F9600 switch and use the SMDI module in Asterisk 1.6.1.x to communicate the calling information needed to make the interplay between the two systems work smoothly. This portion of the project is configured and working fine, as is the programming in extensions.conf. The SMDI work done by Russell at Digium came out really well (thanks). We are having one problem, though. That is, the DTMF interactions are not working consistently from the Fujitsu to Asterisk (particularly the sending of extension number and passcode). Sometimes the system will get just a portion of the extension number or the password and hangup the call before the entering is finished. Sometimes it will work fine, especially if one "dials" slowly. I have to figure that these problems are resulting from a discordance between the DTMF timing settings on the Fujitsu and those on the Asterisk box. However, I am unsure of how to figure out what settings to use. I can certainly view the settings on the Fujitsu, but do not know of how to "tune" the DAHDI settings on the Asterisk side. The options looked limited. Or, conversely, what settings does Asterisk expect to see? If I knew that, I could tune on the Fujitsu side of the equation. BTW, the telephony hardware we are using is a Digium Wildcard AEX800 Board 1. Thanks for any help any of you can provide. - Will
