<p class="MsoNormal">PJSIP … granstream to SIP doorstation works somewhat, I get early video but no audio. If I answer the doorstation before the early video pops up, I get the window in the doorstation that allows me to put a call on hold.<o:p></o:p></p>
<p class="MsoNormal">When I do, and take back off hold, I get audio.<o:p></o:p></p>
<p class="MsoNormal">If I wait for early video on the doorstation and then answer it, the door station never comes up with the menus to put a call on hold. So no audio.<o:p></o:p></p>
