HMR to add public IP in custom header
Hi, I need to know if it is possible to add the source IP address in a custom header to the core, taking into account that this information is not included in the SIP message since it is under NAT
Example of SIP INVITE from access site
Invite from 200.54.78.4 to 190.4.5.10
