This program is a very simple usage example of liblinphone, desmonstrating how to send/receive SIP MESSAGE from a sip uri identity passed from the command line.
Argument must be like sip:jehan.nosp@m.@sip.nosp@m..linp.nosp@m.hone.nosp@m..org .
ex chatroom sip:jehan.nosp@m.@sip.nosp@m..linp.nosp@m.hone.nosp@m..org
