I recently had a similar problem with regards to not being able to receive incoming calls. It occurs after I tried the setting adjustment in the ##778 setting. Under modem I attempted to change the "Preferred Mode" to HDR Only...it however changed the HDR Hybrid Preferred setting to "Disabled". After being told about a few missed calls I changed the "Preferred Mode" back to automatic. However this apparently wasn't enough as I continued to miss calls...I had to log back into the ##778 settings and Modem and change the HDR Hybrid Preferred setting to "Enable". After that I have been able to receive calls.
