Interconnecting between two CUCM

Dears,

 

i am not sure the design is correct or not please help me on this.

 

If i have a CUCM 6.1 on two servers MCS7816H3-K9-CMB2 and two voice gateway and 400 phones are working it.

If i buy a new CUCM 9 and add new phones to it , will i be able to communicate with the phones which are connected on CUCM 6.1.

Hi,If u have a valid ESW

Hi,

If u have a valid ESW contract and UCSS contract with 400 users, then, u can get place the order for CUCM 9 through PUT.You can share the existing licenses for conversion to ELM.

If u do not have the contract, them u need to place order for Migration.For Part Codes, u can involve your Pre-Sales.

You need to change the Hardware for CUCM 9.

 

Also, refer the compatibility matrix for upgrade.

Hi,there is no esw contract

Hi,

there is no esw contract for the existing device, if we have stil we need to upgrade the hardware and it will cost for license migration also

so was deciding if we can buy new hardware with new version and intercluster with the existing system as per design attached will will it work

will the same gateway will be able to communicate with both cucm

Hi Edwin,

I have never seen a single Voice Gateway registering to two CUCM clusters of different/same version at same time.

I would still suggest work with Cisco so that you can work on CUCM 9 and take into account the commercials involved .
