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

I think many people are staying with SCCP when going to 5.x.x.

The issue you have here is that you can not upgrade from 4.2 to 5.x, you can only upgrade to 6.x from 4.2. Right Scott? ;)

  A little background:  We installed 4.2.3 about 8 months ago as part of a pilot program and have a several sites for a total of about 80-90 phones.  We will be adding our main site with approximately 400 users within the next 12 months.  We have one Call Manager Cluster that is sized for all of this along with a Unity server.

  Should we upgrade to the latest 5.X version and consider using SIP?  Is the upgrade a painful process and is there any long term benefit?  I am a little concerned about staying on the Windows platform and the proprietary SCCP protocol.  At the same time, I'm concerned about the reliability of 5.X and the learning curve.

  Any insight would be appreciated.

  Thanks!
