\brief Send DTMF to a channel
\param chan The channel that will receive the DTMF frames
\param peer (optional) Peer channel that will be autoserviced while the
primary channel is receiving DTMF
\param digits This is a string of characters representing the DTMF digits
to be sent to the channel. Valid characters are
"0123456789*#abcdABCD". Note: You can pass arguments 'f' or
'F', if you want to Flash the channel (if supported by the
channel), or 'w' to add a 500 millisecond pause to the DTMF
sequence.
\param between This is the number of milliseconds to wait in between each
DTMF digit. If zero milliseconds is specified, then the
default value of 100 will be used.
\param duration This is the duration that each DTMF digit should have.
