Hi,

Requirement of CTI Application to send DTMF using SIP Circuit to external IVR.

Can any one let me know sample application to test the DTMF digits

So, you want an application that will automatically make an outgoing call and then inject DTMF into the call. Correct?

It is possible to do this using DMCC but I don't see any sample application that is a good match. Most of the sample apps are based on incoming calls or recording. The only sample that I can see makes an outgoing call is the Click2Call sample in the JAVA SDK. I think this allows a user to control an existing phone using a Java app. However, it's GUI based and integrates with LDAP so it may be easier for to to start from scratch.

The .Net SDK includes the DMCC Dashboard. This allows you to manually exercise DMCC functions via a GUI. It also has an Automated Testing feature. This records your actions and allows you to save, edit and play these actions. This would allow some level of automation.
