[cisco-voip] Would you upgrade from 4.2.3 to 5.xx?

[Axel Wilzinski]

Well that makes the decision easy! :)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.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...Thanks again!
