If your SIP Call Control device is a Lync Server, you should not need the full certificate chain installed if the Lync server trusts the Call Bridge certificate. The best way to do this is to create the Call Bridge certificate on the Lync server domain. The reason is that, unlike the Lync server, the Call Bridge does not accept TLS connections from the Lync clients (only from the Lync Server).

However, you may need the complete chain of certificates if you are using other Call Control devices.
