related project: oFono - open source telephony

[Leonard Norrgard]

You'll probably find the oFono project interesting. As they say on
their homepage: "oFono.org is a place to bring developers together
around designing an infrastructure for building mobile telephony (GSM/
UMTS) applications."

oFono itself is licensed under GPLv2, and it includes a high-level D-
Bus API for use by telephony applications of any license. oFono also
includes a low-level plug-in API for integrating with open source as
well as third party telephony stacks, cellular modems and storage back-
ends. Architecture: http://ofono.org/documentation

oFono was founded by Nokia and Intel earlier this year and is jointly
maintained:
