Greetings All!<br><br>While I'm not intentionally trying to start a huge debate...I am interested to hear what the groups opinions are for deploying a Unified Communications Manager Express (CME) with Cisco phones...using which protocol?<br>
<br>I'm starting out right now and the Cisco Voice CCNA book seems to almost exclusively reference SCCP. However, from what I see and hear SIP is becoming more and more prevalent.<br><br>What are the pro's and con's for using SCCP in CME? SIP in CME?...<br>
<br>Any opinions or references to factual information would be great.<br>
