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

[Ocampo, Walter]

I was in a training last week  for call manager 5.1.  I spoke with one
of the Cisco engineers who said Call Manager version 6.0 has been the
most tested one. 

I noticed also that SIP still has some issues that need to be fixed,
especially when they are in SRST mode.

I will also stick with SCCP .

Really the interface hasn't changed that much from what I can see.  They
make it a little easier to find things from one page.  But most all the
things are in the same place.

PS. I'm with Ed and the upgrade process on 5.x.  I'm looking forward to
upgrading this summer.

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!
