<p>*This program is a <em>very</em> simple usage example of liblinphone. *Desmonstrating how to initiate a SIP registration from a sip uri identity passed from the command line. *first argument must be like sip:<a href="#" onclick="location.href='mai'+'lto:'+'jeh'+'an'+'@si'+'p.'+'lin'+'ph'+'one'+'.o'+'rg'; return false;">jehan<span style="display: none;">.nosp@m.</span>@sip<span style="display: none;">.nosp@m.</span>.linp<span style="display: none;">.nosp@m.</span>hone<span style="display: none;">.nosp@m.</span>.org</a> , second must be password . <br/>
*ex registration sip:<a href="#" onclick="location.href='mai'+'lto:'+'jeh'+'an'+'@si'+'p.'+'lin'+'ph'+'one'+'.o'+'rg'; return false;">jehan<span style="display: none;">.nosp@m.</span>@sip<span style="display: none;">.nosp@m.</span>.linp<span style="display: none;">.nosp@m.</span>hone<span style="display: none;">.nosp@m.</span>.org</a> secret <br/>
Registration is cleared on SIGINT <br/>
