System is a 3300 with a MiContact center IVR answering all the calls. All calls arrive via PRI. When calling in from another PRI or an analog line there is no issues, but when I call from a cell phone almost every time I miss the first 3-4 seconds of the greeting. Is there something I can change on the PRI to fix this or is it just a matter of inserting a pause before the greeting in the IVR?
