Paging to Valcom Paging system

Hello I am trying to hookup my asterisk box so that it can page to my existing paging system. I am using trixbox and have followed the instructions here. Except for the compling part, i tried that already and killed my box. I followed the instructions on the wiki and when i call *51 all i get is a dialtone. can someone help please!.

Thanks … sound+card

That is what i found on the wiki.
