<div>Dear All,</div>
<div> </div>
<div>I have a question about the PBX interoperability with CCM. What can I do to make CCM to handle all the call routing even for the PBX end-phone? </div>
<div>One of the solution I heard about is to use SIP trunk connecting with CCM & PBX, but I'm not quite sure how to do that. Any suggestion or comment would be very grateful. Thanks.</div>

<div>Regards,</div>
