[Asterisk-Users] Turn off DTMF recognition pending on CallerID

[Daniel Nyström]

Is it possible to turn off DTMF recognition (and all transfer services etc.) pending on CallerID (or FXS channel)?
Some of the FXS channels I will setup soon, is going to work exactly like POTS.
It will be used by people not knowing their within Asterisk.
They will be pretty confused when "Transfer" is playbacked in the handset. :)
