<div style="text-align: left;">Well that makes the decision easy! :)<br><br>As far as SCCP vs. SIP, I guess I'm just looking at industry trends more than anything. We have been happy with SCCP for the 8 months that we have been using it. I just want to make sure we are making the right choice going forward. From what I can tell, the best choice right now is SCCP, which is fine. I was also looking at the possibility of supporting 3rd party SIP devices such as conference phones, etc.<br><br>My bigger concern is on the OS platform as well as learning a whole new interface. It looks like we would have to wait until a 6.x version to come out anyway, and even then I would want to wait for all the bugs to settle...<br><br>Thanks again!<br>
