Hi, I'm encountering an issue with removing an Identity header in OpenSIPS 3.4. Here’s the situation:
1. An incoming call with an Identity header is received. 2. I perform a `stir_shaken_verify()` and remove the Identity header in a request route. 3. The call is forwarded to an upstream server, but it fails. 4. In the `failure_route`, I need to forward the call to a PSTN number. 5. Before sending the call to the PSTN (in compliance with French STIR/SHAKEN regulations), I need to sign it with my certificate. However, when I call `stir_shaken_auth()`, I receive an error -2 indicating that the Identity header already exists. Despite running `remove_hf(identity)` before calling this function, the header isn't removed, and `$hdr(identity)` still returns the initial value of the Identity header. What is the best way to remove the existing Identity header and re-sign the call? Thank you, Srigo
