ICT (non gatekeeper) between CUCM v10.5 and CUCM v6.2

[Siva Mantri]

Hi 

I would like to setup ICT (non gatekeeper) between CUCM v10.5 running on UCS with CUCM v6.2 running on MCS H7825I. 

Will there be any compatibility issues ?

Is there any special consideration in configuration needs to be taken care ?

Thanks in advance.

Hi Siva,

There are no such known issues for ICT between between 6.x and 10.x versions. You can set it up normally.

Manish is correct (+5), H323 protocol which is used for ICT has matured years ago and hence is compatible with older versions, so just ensure you have proper destinations on the ICT pointing to servers that are in the other side's device pool assigned to the ICT.

If you ever upgrade 6.X cluster to anything 8+ Cisco recommends SIP trunk rather than ICT.

I agree with Chris, 8.x and above should use SIP Trunks.
