If you have a mobile phone with ability do download ringing tones, you can try to create a ringing tone which sounds like Morse Code. I have created one for myself and now my phone rings with my callsing. I have Nokia 6310 phone and created my ringing tone with Nokia PC Composer.
Then I started to look at an option to create Morse Code ringing tones automatically. I looked at various ringing tone formats and thought that RTTTL (Ringing Tone Text Transfer Language) format would be the easiest to use. RTTTL is very simple and Google search will reveal you a number of references to it. I have written a script that creates RTTTL ringing tone, so here we are. I have to warn you that from this point you will do everything at your own risk and I can not be held responsible for any damage you will do to your mobile phone.
Enter Ringing Tone name, this name will appear on your phone after you download the tone to your mobile phone. The name can be up to 10 characters long. Replace CW below with anything you like. I used my callsign.
Enter the speed you want. To keep things simple I used RTTTL beats as the speed. I used 120 beats for my mobile and it sounds OK to me. You can change this value between 100 and 200. I didn't bother to calculate the speed in wpm.
Enter octave. Here is what the definitions are:
RTTTL standard: Octave 5: note A=440Hz, 6: A=880Hz, 7: A=1.76 kHz, 8: A=3.52 kHz
RTX standard (extension of RTTTL): Octave 4: note A=440Hz, 5: A=880Hz, 6: A=1.76 kHz, 7: A=3.52 kHz
Enter the text you want to be converted to Morse Code Ringing Tone, your callsign, for example.
Press "Create Ringing Tone" button.
Your ringing tone in RTTTL format will be generated in the text area below.

Between 100 and 200. 120 sounds optimal to me. |
Enter Octave |

5: A=440Hz, 6: A=880Hz, 7: A=1.76 kHz, 8: A=3.52 kHz |

Select the text above, press Ctrl+C to copy it. You can now launch any text editor (Notepad will do) and then paste the copied text with Ctrl+V. Depending on what you want to do next, save the file with .rtttl or .txt extention.
So, you have the file, what is next? There are a number of ways to transfer a ringing tone to your mobile phone. First I suggest you to check if any software came with your phone (depending on the phone model a cable may be also required). If you have the software and it supports RTTTL then the rest is simple - just follow the instructions in your software manual. I have downloaded the ringing tone to my mobile phone with Nokia PC Tools Suit. If your software does not support RTTTL, you want to use SMS or you want to have keypress format, then you have to convert RTTTL to the format you need.
Here is on-line RTTTL to Nokia SMS converter and you can even e-mail the ringtone to your phone http://ringtonetools.mikekohn.net/rtttl2nokia.php
If your phone software takes MIDI file then try this excellent RTTL to MIDI converter http://www.skybound.nl/cgi-bin/service/rtttl/midi.cgi
This one http://cellphones.about.com/od/ringtoneshowto/l/bl_rc.htm claims that it takes RTTTL input, converts it to some other format depending on your phone type and gives all the instructions what to do next. It is web based and it is free. It apperas to be exactly what you want, but I have not tried it myself.
There is on-line converter here: http://www.convert-ringtones.com/ and it will produce a bunch of files in various formats, but it says that the ringing tone length will be limited to 8 sec. You can try it anyway and you will probably find that it will work out for you. Some of the files produced by this converter are in "keypress" format, i.e. you can manually enter the ringing tone into your mobile. The file extention is .noktxt for Nokia. Please note that I found that if you listen .wav or .midi file it sounds a bit different from the actual ring. It appears that this converter will ignore octave setting and you stuck with the lowest one (5).
There are some downloadable ringing tone coverters. Use Google to find one. Those converters often provide interface to download the ringing tones into your mobile phones. Here is an example http://www.ringtone-converters.com
Enjoy and let me know how it worked for you (if worked at all) - mobile phone types, software and/or technique you used to transfer the ringing tone to your mobile phone.
