Automatic sending "applicationmap" DTMF

I uses Asterisk PBX , i installed a new applicationmap feature with code #1.

how can i send the #1 automatically after answering the call?

I tried :

with feature:

[applicationmap] nway-inv => #1,self/caller,Macro,gonna

but it has no effect, please help

Features are only processed when a bridge exists. The bridge does not exist at the point where those dial options are processed.

What are you trying to achieve by doing this?

You should probably be using the goto or subroutine features of Dial and doing whatever the feature does, explicitly.
