Synopsis:

 Sends arbitrary DTMF digits

Description:

 SendDTMF(digits[|timeout_ms])

Sends DTMF digits on a channel.
A 'w' as digit will cause a pause of 0.5 seconds.
The timeout option only works in CVS after 12-30-04. If not specified, the default value of the timeout is 250 ms (checked on Asterisk 1.4.21.2)

Note: The Dial command comes with the 'D' option that is also able to send DTMF to a channel.
