Disconnected number on every call - Help ASAP Thanks.

All I get is disconnected numbers. I check the list by dialing manually and the numbers are good.
Also I made sure to override the Phone Code to 1 to see if that was the problem its not.
I'm using pots lines. What I think the problem might be is that vicidial is dialing too fast before the line picks up and the 1 is missed.
This happens to me on Manual and Predictive Dialing.
I keep getting the message from the phone company is please dial 1 before dialing this number the tone are for the deaf community.
Please help ASAP I need to get my phone room running again.
Thank you so much for any immediate help
