Does anyone know how to use the Sheared Park Extensions feature (V10) on the GXV3175. Maybe someone could tell me if there is a dial code for a manual park/un-park from the shared park extensions (SP0-SP10). I have some GXV3175 phones and use the shared park extensions on the system from other phones but in the BLF setup on the GXV3175 phones an option for SP exts is not available. I can use the *01 and *11 as a work around but this makes parking calls for theses phones different from the rest. Also requires configuring two buttons rather than one and you do not get the cool red and green light feed back.
