New install , in early December everything working fine until two weeks ago . now it randomly drops calls . Did a system reset , confirmed system ground ran sidetone test . Talking to the women who answer most calls and they say they hear a noise on the line then dead air . I made a call and a minute or so in it dropped and gave me dial tone. Called back and talked for 10 min or so with no drops . One of the women said she timed it and dropped every 6 min while she was on a conference call the other day . Its random not all calls just occasional ones

Century link says they ran extensive tests and nothing wrong on their end . This is a straight wink start T1

I looked at alarms and I don't see anything unexpected

I'm going back tomorrow and I'll give century link and Necntac a call and see what they say



Settings :ESF (24 Multi frame )
B8zs
External clock source
number of ports auto

Trunk timers are all default


Again ,worked fine until two weeks ago , no program changes on my end .

Any suggestions
