What options do I have for using an external ringer, or bell, with the T48G? We're testing these in a warehouse setting, using SfB as our cloud pbx. Unfortunately the ring volume on the phone just isn't going to cut it, and we need to tie in a bell or amplified speaker.

thanks,

Alan

HI Alan，

As the phone can not be able to connect external 3rd party speaker device, so please adjust the ringtone volume to the maximum value.
