Can a CS1K at 7.5 be networked to a CS1K at 5.5?

[umanitoba]

I have two CS1Ks at 5.5...but want to upgrade one to 7.5. The swtiches are networked via IP trunks and the primary NRS would be at the 7.5 switch. Does anyone know if this is possible? Thanks!

Hi,
I have done this where I upgraded my main CS1000E to Rls 7.5 with NRS (no Session Manager). I had a Rls 5.5 CS1000E networked via H.323 trunks. All worked OK.
Good luck

Good afternoon,

We are connecting a CS1000 7.5 against CS1000 4.5 using H323 in a global network, the locals endpoint is registered with the SS, but the remote is not recorded.

Anyone with information regarding the ports must be open on the network to link up the H323 link?

Thanks for the help
