I have a Vodavi STSE with the 24 button set that was being used in a space by one customer and they moved out yesterday taking thier 2 CO's with them, today a new customer moved in so I connected thier 2 CO's that they had moved over from thier old location(that didn't have a pbx) to the vodavi and the phones won't roll to the next line. So basically if I call the main line and I answer, when I call that main line again it just rings and rings. Should thier be any rolling set up on the CO's side? Or should I check to make sure they don't have some setting on thier line that's causing this? I do know when your on line 1 and you call line one, it beeps in the handset your on, but never rings to any of the other phones.

Thanks for any info
