Hi,

 

I need to check source ip of a SIP message and also destination IP to which the message will be sent.

i.e. I will use mediaproxy only if the one of the ip addresses match 10.0.0.0 / 255.0.0.0

 

is it possible ?

 

Thanks,

ilker

In fact, I am not looking for "if address is NATed or not", I need to check if address belongs to my network or not.

 

what do you mean by RFC1918 addresses ?

 

Thanks,

ilker

Why not test for RFC1918 addresses? That's what the onsip.org nat-handling scripts do. A NATed destination is determined by a flag in the location record and the src ip is checked with nat_uac_test().  It will give a more robust NAT handling that testing on IP addresses for parts of the RFC1918 addresses.
The problem has already been solved, why not reuse? ;-)
