"sip show peers" is showing FD_L2 (SIP/54 is registered)

I have tired the above plan with small change 4,n,Voicemail(4) (as there is no gotoif statement)
So:
exten => 4,1,Dial(${FD_L2},20,trw)
exten => 4,n,Voicemail(4)
exten => 4,n,Hangup()

Line 2 is ring OK, and if nobody pickup the phone it goes to "Voicemail(4)" so this part is working; there were no errors on the command line.

But I've tired it again, this dialplan) as before and you are correct something is wrong but command line is not showing any errors:

exten => 4,1,Dial(${FD_L1},25,trw)
exten => 4,n,GotoIf($["${DIALSTATUS}"="BUSY"]?line2:)
exten => 4,n(line2),Dial(${FD_L2},20,rw)
exten => 4,n,Voicemail(4)
exten => 4,n,Hangup()

I've tried: 
exten => 4,n,GotoIf($["${DIALSTATUS}"="BUSY"]?line2)
exten => 4,n,GotoIf($["${DIALSTATUS}"="BUSY"]?line2:)
exten => 4,n,GotoIf($["${DIALSTATUS}"="BUSY"]?:line2)

And I get:

   -- Called SIP/4
    -- SIP/4-00000306 is ringing
    -- Nobody picked up in 25000 ms
    -- Executing [4 at extensions:2] GotoIf("IAX2/home_server-435", "0?line2:") in new stack
    -- Executing [4 at extensions:3] Dial("IAX2/home_server-435", "SIP/54,20,rw") in new stack
  == Using SIP RTP CoS mark 5
    -- Called SIP/54
    -- SIP/54-00000307 is ringing
  == Spawn extension (extensions, 4, 3) exited non-zero on 'IAX2/home_server-435'
    -- Hungup 'IAX2/home_server-435'

So FD_L1 (exten: 4) is ringing for 25sec.; nobody pickup the phone and command line is showing it goes to: FD_L2 (SIP/54) 
-- SIP/54-00000307 is ringing

but in reality FD_L2 (SIP/54) is not ringing at all, it should ring line_2 for 20sec and go to Voicemail but as soon as it prints line:
-- SIP/54-00000307 is ringing

it hangs up the phone.
