[asterisk-users] POTS(FXO) line getting Red alarm after first ring(5 or 6 seconds)

Hello,
I have an OpenVox A400E02 (2FXO) in a box running Debian 6.0.2 running 
Asterisk 1.8.6.0.  I have to POTS line on it from Verizon in Virginia, 
USA.  Whenever I place a call to one of the two lines I get a red alam 
and then it clears and repeats this till I hang up.  There is no caller 
ID on the Line (boss won't pay for it).
Any help is most appreciated.
TIA,
JohnM
