[cisco-voip] Calling Name lost inbound from PSTN over Intercluster Trunk with QSIG

[Linsemier, Matthew]

Jason,

All other Calling Name works correctly back and forth over the ICT… so phone to phone, Unity, Meetingplace Express, UCCX, all works as expected.

Since inbound Calling Name 6.1 cluster works fine to a phone ON that cluster, I know it works.  I suspect that because the way that UC is processing that call and pushing it directly to the ICT that it doesn’t / can’t process these features . The ICT with QSIG enabled does not support setting the Facility / Display IE features.

Depending on switch/telco could also be a Facility IE vs Display IE issue, I would pull debug q931/debug ccm-manager backhaul packets/ CCM traces and look.  Do 7900 phones on both sides show name on incoming call from PSTN? It’s just the ICT that isn’t passing name across. Does the ICT work 7900 Phone to 7900 phone with name delivery?

What was the answer you got in 2008?   In order for calling name to be delivered to the remote cluster the originating cluster is going to have to send it, and the remote is going to have to honor it.

How is the name delivered on the 6.1 side and what do ccm traces show for what it sends on to the 8.6 cluster?

All,

I asked this question back in 2008 and I am wondering if anything has changed since then.

I have two Unified Communication clusters, one on 6.1 (existing) and a new one on 8.6 (new greenfield cluster).  They are currently connected via a Intercluster Trunk using QSIG.  Everything is working well across the trunk from internal calling name and number as well as MWI.

The issue we are having is as we move users from the old cluster to the new cluster, inbound calls from the PSTN on the old cluster (via MGCP gateways that are still registered there) destined for users on the new cluster will lose calling name.  This means that during the migration (which will be going on for 3-4 weeks), users on the new cluster will lose Calling Name from outside PSTN users.

PSTN GW – MGCP --> UC6.1 <--- ICT ---> UC8.6 --- Phone

Is there any way to fix this?

Sincerely,
