[asterisk-users] Strange SIP response

[Joe Dennick]

Have you done a "show channels" to see if Asterisk thinks that SIP 
Device is in use?  I experienced this problem once after doing a 
Blind-Transfer from a Cisco 7940 SIP Phone.  The transferred call had 
long since been disconnected, but the Cisco phone thought it still had 
control of the call, so it wouldn't accept any new calls.  The only way 
I was able to get past it was to re-boot the Cisco phone.
