[OpenSIPS-Users] lookup("location") extract received field value

[Satish Patel]

Hi,

I have following User registred over public IP but that client doesn't
support STUN so contact info showing private IP "192.168.1.6"

lookup function default extract "Contact:: sip:1001 at 192.168.1.6:27098"

Is there a way i can extract  "Received:: sip:173.XX.XX.215:27098"  so i
can create new URI and send call to that?

if (lookup("location")) {
    ..
    ..
}


[root at sip ~]# opensipsctl ul show
Domain:: location table=512 records=1
        AOR:: 1001 at sip.example.com
                Contact:: sip:1001 at 192.168.1.6:27098;rinstance=e223da1c59d774db
