[Asterisk-video] Variable Pass Through h324m_gw()

[lemonash]

Hi folks!

The following is my dialplan:
[test1]
exten => 120,1,Set(Digit="123")
exten => 120,n,NoOp(${Digit})
exten => 120,n,h324m_gw(ds at test2)

[test2]
exten => ds,1,h324m_gw_answer()
exten => ds,n,NoOp(${Digit})
exten => ds,n,Set(Name=${Digit})


The variable Name in test2 is NULL!
How can I get the variable from test1?

Thanks!
