[Asterisk-Users] Zombie SIP channels

[Pedro]

Does anyone know how to kill a zombie channel?

Here is what I see on a show channels:
--------------------------------------------------
show channels
        Channel  (Context    Extension    Pri )   State Appl.        
Data
SIP/frontdesk-72c7  (customercontext               1   )      Up
Bridged Call  SIP/frontdesk-0461<ZOMBIE>
SIP/frontdesk-0461<ZOMBIE>  (customercontext 100          1   )   
Ring Dial          SIP/frontdesk|20|t
2 active channel(s)
--------------------------------------------------

No one is on a call - how can I get rid of this without restarting asterisk?

Thanks!

Pedro
