[Asterisk-Users] Zombie SIP channels

[Pedro]

I tried to send this earlier but does not look like it went through
for some reason.  If you get this twice - my appologies.

Does anyone know how to kill a zombie channel (and why do they pop up)?

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
