we have cisco call manager express with a sip trunk to a service provider.
all calls work
dtmf internal to internal works
dtmf external to internal works
dtmf internal to extenal does not work.
has anyone done anything like this and is it possible on express?

What type of dtmf are you using on your dial-peer?
Could you please upload your show run?
