Are there any alert tone settings for this phone? IE: is there a missed call alert or a voicemail alert settings? in other words is there a setting where I can go in and set a reminder that I had a voicemail or missed call? a lot of phones are going away from that but it is nice if the phone was on on the counter and I didn't know that I missed a call. I also checked the alarm application and thought that the choices for the tone were horrible. is there any way I can add to the selection?
