Question
Custom Ringtones
The handsets (FON450i) reportedly support RTTTL ringtones. I created a text file, entered the tune, and saved the file. When I try to upload I get an invalid format. What extension should the file have? Since there is a 5 (custom) ringtone limit, how do I check or erase an existing tone? Are there changes outside of the standard specification we need to conform to (such as case-sensitive input)?
