[asterisk-users] Sending Calls via SIP trunk from two different IP addresses from same Asterisk Machine

[bilal ghayyad]

Hi All;

I can assign for my Asterisk Machine a two IP addresses (xxx.xxx.xxx.yyy and xxx.xxx.xxx.yyz), how can I use these two IP's so I can let one call sent with a source IP address xxx.xxx.xxx.yyy and another call to be sent with another source IP address xxx.xxx.xxx.yyz, I need this because I need the side to authorize my calls by the IP address, and some calls to be authorized with the first IP address and other calls to be authorized with another IP address, ofcourse I have some reason for this. 

The idea is: how to control the source IP address that I am sending from it to the other side?

Can I determine the source IP address of the SIP trunk while I am configuing my SIP section for that connection? What about the bindaddress?

Any help?
