Been trained on IPO 500 about 8 yrs ago by Westcon. Never got the chance to put one in till now. Using manager 10.1,Admin 9.0, went to user and added the line 703. Look at the phone seems to be there. Also put line 703 in service. Got a solid green light & when I push it beeps. No dial tone. What am I missing.
