I am new to setting up FreePBX and have been trawling through the forums looking for some help with an error that I am getting. Inbound and outbound calls are working fine BUT calls to some 3rd party client IVR systems result in the call not triggering their IVR. The result is a call that has to be dropped.
I have seen in the FreePBX configuration, “somewhere”, a setting which alluded to improving compatibility with this, but I have not been able relocate and to find a solution.
