Hi! I have a h323-trunk between UCM 7 and CME. In CME I have a ephone-dn 100 with label "TEST". On UCM I have phone with line 200 - Display (Internal Caller ID), Alerting name "CENTER". When I call from UCM to CME phones, I can see dialed number 100 and label TEST on my phone. But on CME phone I can only see calling number 200 without any info from Display or Alerting. How can I fix it to transfer Display and Alerting name label to CME phones?
In the gateway configuration in CM, make sure the the Display IE Delivery is checked for call routing information - outbound calls.
Hope it helps, please rate if it helps.
