<DIV><FONT face=Arial size=2>Is possible put in conference a sip phone where
there are two calls (one active and the other held) from Asterisk? Is there any
SIP header to activate the conference in a SIP phone remotly?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>El escenario es:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. SIP A calls SIP B: call 1</FONT></DIV>
<DIV><FONT face=Arial size=2>2. SIP A calls SIP C: call 2 --> call 1 held;
call 2 active</FONT></DIV>
<DIV><FONT face=Arial size=2>3. ASTERISK APPLICATION notify SIP A for put call 1
and call 2 in conference.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
