Hi Community,

My provider (ISTP) is asking me to send the Invite, in this SDP message to appear the IP (189.204.181.121) of the interface that is connected to the service in the from parameter.

Have a look at this document, it contains amongst other the information that you ask about. https://www.cisco.com/c/en/us/support/docs/voice/ip-telephony-voice-over-ip-voip/211306-In-Depth-Explanation-of-Cisco-IOS-and-IO.html
Apart from this you should take a look at the SIP profile test tool that Cisco has. It would help you to get this done.

Have a look at at this post for some ideas on how to achieve what you ask about. https://community.cisco.com/t5/ip-telephony-and-phones/change-invite-package-header-with-conditional-sip-profiles/m-p/4286535
It is not a direct match, but the overall concept would be the same.
