ofono.org mobile telephony stack
oFono is a stack for mobile telephony devices on Linux. oFono supports speaking to telephony devices through specific drivers, or with generic AT commands. oFono also includes a low-level plug-in API for integrating with other 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)." This package includes the core daemon.
