Watch out for the size of the BFL packets. They could very well not fit through the SBC if it is configured improperly or by default. I am quite sure ACME default breaks it while Metaswitch Perimeta's default works.

This is still a PBX-level feature, and any "SBC" should just pass the
relevant subscriptions and notifications through. SBCs do not provide
any application-level functionality that relates to handsets or user
