[asterisk-dev] How to get SIP packet source ip address in asterisk application

[ast guy]

Hi,

 I have made an application an asterisk. Can any one tell how do I get
the source IP address of the SIP packets inside my app_Application()?
Application only gets the ast_channel variable and *data passed to it.

SIP Call is being forwarded to my application from some Service
Provider. So when app_Applicaiton() is in execute state then I want to
get the sip source packet ip address and then authenticate it.
