I assume from your description that phones not using that load have the option to save the handset volume which tells me you are using CallManager 3.1. If you are using CM3.1 you don't need to use those loads anymore, the default 3.1 loads work with SRST.
Also, in CM3.0 (what the P003D302 load was built for originally), to save the volume you must adjust it, press Settings, then Save.
