Error 629

1.  Make certain that you are dialing the correct ISDN number and that it does not contain illegal characters. Is it a local call? If not, verify that the user is certain that they have clear channel Long Distance service.

2.  Verify username/password.

3.  Verify that the user's account is setup for ISDN. (ISP/auth end)

4.  Verify the POP isn't down and that it is accepting ISDN connections

5.  Verify the ISDN Router / T/A's settings (SPIDs, etc)

6.  This could be a line issue. Have the telco perform a loopback test
