== Subscribing to Buddy's Presence Status ==

To subscribe to buddy's presence status, you need to add a buddy object, install callback to handle buddy's event, and start subscribing to buddy's presence status. The snippet below shows a sample code to achieve these.

 {{{
#!python

class MyBuddyCallback(pjsua.BuddyCallback):
    def __init__(self, buddy=None):
        pjsua.BuddyCallback.__init__(self, buddy)

    def on_state(self):
        print "Buddy", self.buddy.info().uri, "is",
        print self.buddy.info().online_text

try:
    uri = '"Alice" <sip:alice@example.com>'
    buddy = acc.add_buddy(uri, cb=MyBuddyCallback())
    buddy.subscribe()

except pjsua.Error, err:
    print 'Error adding buddy:', err
 }}}
