Description:Hello, not sure it's a bug.

I have queue with agi scipt. When I call to queue and then hangup, I can't get variable set in agi script.
But if agent hangup variable is available in dialplan.

extensions.conf
{noformat}
[test]
exten => _X.,1,Answer()
same => n,Queue(it-support,cF,,,,1.py)
same => n,NoOp(TEST: TICKET_ID ${TEST})
same => n,Hangup
{noformat}
1.py
{noformat}
#!/usr/bin/env python
from asterisk.agi import *
agi = AGI()
agi.set_variable("_TEST", "123456")
{noformat}

If caller hangup:
{noformat}
<SIP/be-00000000>AGI Rx << SET VARIABLE "_TEST" "123456"
-- Executing [9656@test:5] NoOp("SIP/00132-00000002", "TEST: TICKET_ID ") in new stack
{noformat}

If agent hangup:
{noformat}
<SIP/bee-00000007>AGI Rx << SET VARIABLE "_TEST" "123456"
-- Executing [9656@test:5] NoOp("SIP/beeline-00000007", "TEST: TICKET_ID 123456") in new stack
{noformat}

This is not a bug.

# Channel variable inheritance happens *only* when a channel is created by another channel.
# The {{1.py}} AGI script runs on the *caller* channel after the *called* channel answers but before they are bridged.
# The *c* option has the *caller* channel *continue* in dialplan at the next location when the *called* channel hangs up first.
# The *F* option has the *called* channel *start* executing in dialplan at the next location when the *caller* channel hangs up first.

Your {{1.py}} AGI script is setting the channel variable on the *caller* channel *after* the *called* channel is created and answered.  Under these conditions you cannot expect the *called* channel to have that channel variable set on it.

So there is no way to get varibales if caller hangup first? :(

You need to rethink what you are trying to accomplish.  You need to remember *who* is executing dialplan.  You could set channel variables on the calling channel before he enters the queue that will then be inherited by the agent's channel.
