Try dialing back into the PM3 from itself (i.e attach <port> then dial).
Of course, this won't work if you have the line setup for incoming only
though.

If you are seeing the username show up with a "DISCONNECT" status, this
usually means an authentication problem. Make sure that the Ascend is set
up to "Send PAP" but not "Recv" or do CHAP. Also, a "set console", "set
debug 0x51" would probably be very helpful, since it will show you exactly
what is happening during the login. I haven't seen the "Protocol Error"
message before, that is coming from the ISDN module.

They are not completing authentication then. Check above mentioned
settings on the Ascend, as well as the user's RADIUS entry.

Yes. Nope.

This is in the manual. Depends on your setup, most likely no.
