My LINE PORT digit map is default.
(xxxxxxxS4|1xxxxxxxxxx|xx.)
In fact, Physical Interfaces>Line Port is all default.
After I read your message I realized I didn't move my DSL filter to the OBI. That seemed to clear up the static.
I do have sp2 configured to calcentric to use as my 911 service once I ditch my land line. Obitalk set up this PHONE Port map for me.
{911:sp2},{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
