<div>Hi,<br>
<br>
We're in the middle of a Microsoft OCS POC integrated with UCM 8.0. I can make internal and external calls from OCS using UCM as my gateway, but calls are dropped as soon as they're answered. Has anyone out there come across a similar problem.<br>
<br>
Kind regards,<br>
<br>
Sechaba Mokoena<br>
