Hewlett-Packard took a major step Monday in trying to convince telecommunications companies to embrace Linux, releasing a software kit to let those companies develop phone software that runs on Linux servers. The Linux version of HP's popular Opencall SS7 product isn't yet finished, but a software-development kit, along with new telecommunications-specific Intel servers lets customers get started testing their software, said Martin Fink, general manager of HP's Linux Systems Operation.
