I think I found the file, extensions__20-baseplan.conf, would this get overriding or would it be safe to add the header there?
Header in the file doesn't appear to be written by Vital so my guess is it will be ok?
Ok, this is something that cannot be add-ed trough VitalPBX, however, you can add your own headers on base plan, as you mentioned, however, this will be overwritten on the next update.
What we're going to do for the next version, is to add a new module to add headers for the intercom feature.
@ing-joserivera26 Thanks, I'll keep in mind that the file will get overwritten on the next update if the new header module is not out yet.
