<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>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!<o:p></o:p></span></p>
