[asterisk-dev] How to get IP Address from Guest Call ?

[Dome Charoenyost]

Dear All,

I try to get IP Address from guest call from ${CHANNEL}   but i got my
Asterisk IP Address .
example :
Executing [66819842912 at ael-dome:1]
Verbose("SIP/203.149.xx.xx-082787c8", "SIP/203.149.xx.xx-082787c8") in
new stack

203.149.xx.xx is Asterisk Box not  Caller IP

How to get Caller IP ?

Best Regard.
