CCM version: 184.108.40.2060-3
Gateway: 2800 12.4(17) EnterpriseService
The caller name display on IP phone for all incoming calls from outside is missing the first letter, whatever the length of name. Debugging q931 in gateway, the names sent in from PRI are correct.
There is no problem with internal calls.
Thank you for any helps.
Here's a suggested solution for you to put to the test.
1. Change the switch-type in the IOS gateway to Primary-dms100
2. Change the switch-type in gateway's configuration in the CallManager configuration to primary-dms100
3. Ensure that the option 'Send Extra Leading Character in Display IE' is checked in the gateway's configuration in CallManager.
4. Test inbound calls for correct caller name
