good morning,

we have some problem with SIP channel ZOMBIE.

in particular we notice that using the *8 to pickup a call sometime happen that capture a wrong call.

the script is:

exten => s,1,SET(GLOBAL(PICKUPMARK)=${MACRO_EXTEN:${ARG1}})
exten => s,n,Pickup(${MACRO_EXTEN:${ARG1}}${TL_DASH}${tenant}@PICKUPMARK)
exten => s,n,Playback(privacy-incorrect)
exten => s,n,Hangup

following the error
in this case extension 655 is making an external call.
simultaneously extension 432 try to capture the call ringing on extension 427.
as you can see from the log then extension 432 is connected with extension 655
the sip channel started from extension 655 have the ZOMBIE state.
