Unity Connection Transfer calls across ICT

[putney_m]

I am working on a system where they have a unity connection 8.6(2) server that has a system call handler configured for external voice mail access. They would like to be able to have the users call in and enter the extensions of users on a remore CUCM cluster and be routed across the Inter Cluster trunk to the remote cluster. I have the system setup to allow the caller to enter the extension of users not associated with a mailbox and I have configured the transfer rules to allow the pattern defined for the extensions. However it still fails.

Any help would be greatly appreciated.

Thanks,

Michael

Michael,

Ensure the CSS assigned of the SIP trunk (if using UCXN SIP integration) or voicemail ports (if using SCCP) has access to a partition that the route pattern pointing to remote cluster is assigned to.

Thank you, that was the problem.
