I installed a new 3x8 expansion card in this system this AM and now my single line devices won't access the line group by dialing 9. The proprietary phones can dial nine and get out OK. Also with single line equipment I can access the lines using 81, 82, or 83. (it's a 3 line system) When I dial nine it stops dial tone but no line access. Program 419 for line access shows all enabled. I think the dtmf receivers are ok because dialing numbers stops dial tone. Any help would be appreciated.
Thanks
