*This program is a _very_ simple usage example of liblinphone,

*demonstrating how to initiate SIP subscriptions and receive notifications from a sip uri identity passed from the command line.
|
|
*<br>Argument must be like sip:jehan@sip.linphone.org .
|
|
*<br>
|
|
*ex budy_list sip:jehan@sip.linphone.org
|
|
*<br>Subscription is cleared on SIGINT
