[OpenSIPS-Users] Opensips 2.2.2 and top hiding

[Răzvan Crainea]

Hi, Denis!

Are you modifying the $ru/$rd variables anyhwere in your script for that 
ACK? I am seeing the R-URI of the ACK going to 3.3.3.3:5068:
ACK sip:3364021 at 3.3.3.3:5068 SIP/2.0.
However, it should be:
ACK sip:3364021 at 4.4.4.4:5060 SIP/2.0.

Can you try printing the $ru variable just after the 
topology_hiding_match() function?

Best regards,
