DTMF doesn’t pass between servers/nodes on AllStar. Instead you
- Connect to the other node with *3<node#>
- Then take command of the other node with *4<node#>
- Send any commands you wish to the other node
- When done, return command to local node with the pound/hash DTMF #
- Disconnect form the other node with *1<node#>

However there is a way to replace links that will pass DTMF. That requires RTCM hardware. See
Another approach is to install Allmon2 and control your network on the web.
