Clear idle VTY sessions
I had this once with a 7500 and a friend at Cisco told me this procedure. I'm not sure if it would help you though. I had an idle session in "show users" output.
To clear the idle session, I typed "show tcp brief". My friend said the stuck one should be in "ESTAB" state, but the one I cleared said "LASTACK", so you can always go by the foreign address. It's better to kick people off temporarily than to have to reboot the router just to clear a stuck VTY session.
To clear the session, type "clear tcp tcb xxxxxxxx", using the hexadecimal TCB address at the beginning of the line from show tcp brief. Then check show users output to see if the session has disappeared.

T I P : To simulate a phone call being made from a PBX for testing purposes, type the command:
csim start XXXXXXXXX
where XXXXXXXX = the phone number
you want to test
Then you can see if your voice-over-IP (VoIP) configuration is correct on the router. Make sure that you have done a write memory recently, because this command can sometimes crash the router. [csim is a "hidden command" and should be performed from a gateway router.]
