oFono - Collaboration from Intel & Nokia

Intel and Nokia have announced a joint partnership today to develop oFono, an open-source telephony solution. The oFono software stack is GPLv2 licensed and includes a high-level D-Bus API for use by other telephony applications and a low-level API for communicating with cellular modems and other devices.

According from oFono official website, oFono.org is a place to bring developers together around designing an infrastructure for building mobile telephony (GSM/UMTS) applications. oFono.org is licensed under GPLv2, and it includes a high-level D-Bus API for use by telephony applications of any license. oFono.org 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. The plug-in API functionality is modeled on public standards, in particular 3GPP TS 27.007 "AT command set for User Equipment (UE)."

oFono aims to make writing telephony applications as easy as possible. Thus oFono will take care of the core logic, including things necessary for standards compliance. This will allow application writers to focus on what they should be doing: presentation aspects and funky animated UIs.
