okay, I hope I'm not steering you in the wrong direction but you said you got dead air when you dialed the access code. NTP states that the options (depending on how your cust. data block is configured) you will get if you are blocked from that route are either overflow tone, attendant or recorded announcement. I would try changing the TGAR on the phone to 0. Again, though, are you sure you're getting dead air and aren't actually connected to your paging system? also, since your attendant can access the paging please post that TN as well.
