cannot delete call history and sounds like 2 different phones ringing at same time on outgoing call.
gateway ram overloaded ? used for business calls. hundreds a day. cannot delete or move to trash call history-" landline " type phone plugged directly into phone jack back of gateway. many call outbound - here 2 different phones ringing same time, even a phone ringing and diconnect message AT SAME TIME. no battery in this gateway to take out to clear " phone call history storage and cant clear call history logged in to xfinity voice connect. no option to delete call history or move to trash. make 100's of business calls a day so 10000 plus calls on call history. reset gateway no effect. reset gateway to factory default no effect either.so far comcast tech support useless on this issue.
