Hello,
I just added a pseudovariable to get the ip/host address from dst_uri.
Now it should be less complex to do the check.
avp_printf("i:20","$dd");
if(avp_check("i:20","eq/$src_ip")) {
# src_ip is the same with destination ip
}
Fore more see: http://openser.org/pipermail/users/2005-August/000681.html

A small errata, to match an IP address:

If ouy use fix_nated_register, it will not work. We would need a
pseudo variable which points to the received-socket. Maybe the core
developers can help you on this.
There is a pseudo variable $du that points to destination uri
(dst_uri filed of sip_msg structure - the address where the sip
message will be sent after a loose_route() or lookup() request for
callee behind the nat).
So, if the callee is behind the nat, the dst_uri is set to the
address and port of the NAT. To check it, copy $du in an avp, use
avp_subst() to extract the ip address and and compare it with src_ip.
avp_printf("i:20","$du");
avp_subst("i:20/d","/.*([1-9][0-9]{1,2}\.[1-9][0-9]{1,2}\.[1-9][0-9]{1,2}\.[1-9][0-9]{1,2}).*"/\1/);
if(avp_check("i:20","eq/$src_ip")) {
# src_ip is the same with destination ip
}
Looking at this issue, I am wondering if worth to add the
pseudovariables $dh and $dp for destination host and port ... Also I
am considering to change a bit the $du reference so when the dst_uri
is not set to point to request URI. Would be these changes usefully?

hi all,
Thanx Klaus.
Sorry to ask a question again related to the same problem. I had
already tried writing the avp_write after lookup but even that
causes a problem.
When avp_write is done it writes the private IP address of the
callee while the source_ip is the IP address of the NAT. I beleive
this IP address is written because of the fix_nated_contact.
Again, when avp_check is done, it returns false and again the RTP
session gets started. IS there any way out to this problem.
Thanx again..
Jayesh
