I have the off hook preference btn enabled.
Flexible Btn. assign I put in(01),(3),(GG),HOLD GG=01 for Ln. Grp 1. I also tried to assign a CO line button (01),(1),(LLL)=003 for Line 3.
I go Off hook and get system DT, hit 9 and go to the last line in line grp. 1

What exactly are you trying to do? You want an analog phone to go off hook and grab a co line?

Flash 50 page b button 10 programming dial 011 hold
flash 50 page b button 11 programming dial 01301 hold

I see where I was going wrong now, I have one analog sta. for the Point of sale, credit card machine and another for a fax. both are used for outgoing only, from an unattached back bldg..
Thank you,
Gary
