Hello, <br><br>     in my test code that copy from
TelepathyQt4\example, i want request connection use some sip
parameters, but i got some error &quot;org.freedesktop.Telepathy.<div id=":3r" class="ii gt">Errors.InvalidArgument and invalid SIP URI&quot;, and on other side, i got connection successful if i used other function <span style="color: rgb(255, 0, 0);">dbus_init()</span>
with same sip parameters that write by myself. i don&#39;t know why it&#39;s
happen if i use TelepathyQt4 lib?  Could anyone give me some
suggestion?  thanks very much! attachment is my code.<br>
