[Tobivan_Helden_2]

Good day, Gents,

Want to ask what can be advantages if I upgrade Call Manager software

from 4.1.3 sr 4d

to 4.2.3 sr 2

Are these advantages can be essential or not ?

Does it make sense ?

I mean is this a fritterware ?

Thank you.

It really depends on your needs. Here are the new capabilities that CCM 4.2(3) has:

Keep in mind that if you upgrade to CCM 4.2(3) you won't be able to upgrade to CCM 5 since is not on the compatibility matrix:

Hi Tobivan,

Just to add a note to Jorg's great info (5 points for your continued good work Jorg) This upgrade is certainly not essential. The 4.2 release does add some really great features (marked with **) If you do not have the need for these changed/added features I wouldn't upgrade to CCM 4.2. It sounds like soon to be released CCM 6.0 might be worth waiting for.
