Switched servers, new install.. Paging is not working?

I do not know what to do. I had paging working flawlessly on my last server, using the same config on the phones, but when I go to page I get this error? The phone just gives me a busy signal. Any idea’s on where to start or how to fix? I uninstalled and reinstalled the paging module which fixed it a little (Prior to reinstall when I’d dial *54, I would get nothing, but now it tells me “PAGING IS ENABLED”) But I cannot page?
