Conference Call and Dial Tones

[workobaw]

My workplace just recently deployed 3CX with an Enterprise license. We have found while on a conference call, that we aren't able to interact with IVR systems - the dial tones don't register in the call. Is there a setting in the 3CX system that affects this so maybe I can turn this on, or is this just not available because of how Conference Calls are handled by the system? Any info would be appreciated. Thank you.

That is correct, due to the way Conference calls are handle internally, DTMF cannot be sent outward from within a conference call. You would have to make a separate call directly from the extension to the external number, go through the IVR and then, once the callee answers, transfer the call to the conference.
