CMS IVR keeps saying "Please enter your caller id..." when called from PSTN. But calls to IVR works for DTMF, entering caller ID(Meeting ID) then joins the meeting.
Solved! Go to Solution.
I have the same issue, works perfectly dialing the IVR from internal, but calls coming in from PSTN, keep asking for Meeting ID.
have tried changing the dtmf on the cms trunk from CUCM, no difference.
