<div>Hi Guys</div>
<div> </div>
<div>I get some problems while configuring the UC500 to work with Polycom VTX 1000. The Polycom is using analog line. </div>
<div> </div>
<div>The Polycom connects to the FXS port of the UC500, by using stcapp, the polycom can dial/receive calls. The problem is if the call is initialized from the polycom, I cannot build up a conference (press the CONF button won't hold the call and switch to another line). But if the polycom receives a call, it will build up a conference by pressing the CONF button. Also the max party in the conference is 3 (including the polycom), is it related to the "dual-line" for the ephone-dn? any configure to increase this?</div>
<div> </div>
<div>Anyone has any idea? Let me know if you need any configuraiton.</div>
<div> </div>
<div>Thanks a lot!</div>

<div>Regards,</div>
