I have a customer that has added a new small
company inside his suite only 2 lines.he wants
to add these 2 lines to his existing ipk system there is a 8 port co line card and he has 6 existing co lines.He does not want the voicemail to pick up on these 2 new lines he has ATT voicemail and he wants these to stay the same the problem is that the voicemail from the IPK is answering.

Question:how do i disable the co port 7 and 8 so
that the ipk voicemail does not answer.
