Hi guys,
Where can I find information about GSM codec patents, fees or other
legal information?

I'm interested in develop a VoIP software and I'd like to use GSM codec.

Thanks in advance,

Where would be a good place to look for patents on ETSI specs? www.etsi.org maybe? :-) They do, in fact, list all the people who claim IP rights over each spec. They don't spell out all the details, though. I doubt there are simple licencing programs for using these things in anything but a GSM or UMTS system. That is the only place most of the codecs have been deployed.

The original 06.10 codec, which * supports, seems to be free of patent problems. Its just too old to have any. :-) Philips used to claim one, but I think its safe now.
