As you know by, I’m working on integrating Asterisk for my employer. One of the uber-cool things that you can do with most SIP phones is upload custom ringers. Some you can upload RAW MP3 or WAV files, but others (like the Sipura-841) require you to upload it in a special format. While I was browsing around grabbing the latest firmware for my testing phones this morning, I saw that Sipura provided a tool to do that, so now all I need is a WAV file worthy of being a ringer.
Enter James Anderson and his ’24′ ringtone website.
Are you sad enough to want to reproduce that distinctive CTU ringtone from the TV series ’24′ on your mobile phone?
Well, I am. So I worked out the RTTTL code needed to get it on my little Nokia 8210.
But that was just the start of the story. Ever since I posted the code here back in 2003, along with the reference samples I used in order to work it out, a lot of equally sad people have sent me versions of the ringtone in different formats.
So here they are, for all your hey-look-at-me-I’m-Jack-Bauer needs:
I downloaded the WAV and converted it to a Sipura ringtone. Now, we won’t be using the SPA-841′s here at our corporate office, and I want to be Jack Bauer’ish, so I pulled out my Bluetooth dongle and pushed the WAV over to my Motorola E815. Now maybe Bonnie will believe me when I tell her that I work for CTU.
Haha..one day I’ll let you play with a vest and a holster and we’ll call you Jack for a day.
*laff*
Can you post a link for the Sipura tool used to convert from WAV to the specific RAW file format required? Is the RAW format similar to the format used for Cisco ringers?
————————
Raw PCM (no header)
8000 samples per second
8 bits per sample
uLaw compression
Maximum ring size — 16080 samples
Minimum ring size — 240 samples
Number of samples in the ring must be evenly divisible by 240
Ring should start and end at the zero crossing

Thanks!
