________________________________________________________________________________
US Cellular & T-Mobile customers calling in to MU Health Care and MU Campus call centers are currently unable to make keypad selections when prompted.

Other cellular providers have not acknowledged this issue, but there have been sporadic reports today of similar issues for AT&T customers.
