Hello, I am trying to use a Callback system that return the call to some number then give it a dial tone with DISA. The callback works well and i can hear the dial tone, the problem is that DISA doesn't do anything when i press any extension number of the current context and hangs the call up after few seconds. If i use callback just to return to the number then call an extension (ex: a sip phone) it works fine, do you know if there is some incompatibility about DISA + Callback? Obs. I use DTMF signaling.
