CUCM/SME/Expressway Modify Inbound/Outbound SIP Domains and SIP headers

For Large Deployments using multiple domains, and routing with Session Management Edition, it would be very helpful if CUCM and Session Management Edition, SME could modify both inbound and outbound To/From SIP Domains. Expressway can Modify the To Domain, but not the From Domain, or maybe its the other way around, but unfortunately, one of the reasons our customer is using a competitor SBC is for SIP manipulations such as Inbound/Outbound To/From SIP domains and other SIP Headers. I know some of this can be done with Expressway, but it is limited. I know that some of this can be done with LUA Scripts on CUCM, but it is very difficult in an environment like this. And we can't use cloud calling with this customer because they are in an Air-Gapped Environment.

    What is the use case to modify the SIP headers?
