I encountered the same problem, and first solved it by using
"BackGround" to play a recording of a dial-tone, as "Playtones"
doesn't do anything with any digits dialled while a tone is beeing played.
A while ago, I made some modifications to "Playtones" to allow it to be
interrupted by dialling a digit and behave very much like "BackGround"
in that respect. The patch to add this new app, called "PlayDialtone", is
attached.
