[asterisk-users] Inserting a wait in a sip dial SOLVED (kind of)

[Steve Murphy]

Dave--

I remember adding a feature a long time ago for snoms, to the source code,
to send dtmf out for some button press on a snom phone, in the 'outward'
direction,
I think to activate a feature or somesuch. (Boy, is my memory hazy!) At any
rate, I was able to
inject dtmf, but I had to do it in the source. AFAICT, there is no app that
do this explicitly; and Murphy's Law would state that even if a dialplan app
existed,
it would not get run at the time you need to be run.

So, if you found a workaround, and it works, it won't matter how pretty it
is. Magic
is Magic.

And speaking of Murphy's Law:

Enjoy it while it lasts, because, sure as death and taxes, someone will fix
a bug
somewhere, and you'll lose an undocumented feature ;)
