Asterisk is probably dialing to quickly and the CO is yet ready to receive
dtmf digits. Rather common problem. Insert a "w" in your dial string
just before the $EXTN (or whatever you're using for a string).

The "w" is not really documented in the 'show application dial', but it
does insert a delay of about 250 milliseconds. If that doesn't work, then
try multiple w's (as in "www").
