I’m using the dRouting module. Is there a way to store the realm using this module?
Also, I don’t think I know the realm until the first time I send a Register or Invite to the carrier. I could guess the realm, but we want to make sure we handle edge cases where the name of the realm is different then the domain name of the carrier.
