Attendant Console 184.108.40.206
Prescence also installed and working to AC
4 digit dialing
CUCM users synced from AD/LDAP
In the Attendant Console client the users phone icons all showed a red X or cross. The Presence Icon was working.
The LDAP server has 10 digit phone numbers. CUCM users therefor have 10 digit phone numbers in the user dB. Phones have 4 digit numbers. no big deal for CUCM. Other apps require 10 digit numbers in LDAP.
Updated LDAP with 4 digit numbers in the IPPhone field.
Changed the LDAP sync in CUCM to pull the IPPhone field for the phone number (to get 4 digit)
Stop and started the LDAP process on Attendant Console to get the 4 digit numbers from CUCM. (instead of 10)
Phone status now working in Attendant Console for the vast majority of phones.
(no longer need 10 digit to 4 digit translations in CUCM for the internal numbers when directory dialing on the phones too)
I was facing the same issue in my lab. The reason i was facing the red X cross on the phones was due to the phone model mine was 99XX series . We need to assign additional CTI roles to the application user.Apart from CCM super user and std cti enable.
Standard CTI Allow Control of All Devices
Standard CTI Allow Control of Phones supporting Connected Xfer and conf
Standard CTI Allow Control of Phones supporting Rollover Mode
Standard CTI Allow Reception of SRTP Key Material
Also the issue may be with the wrong mac address.
Go the console and click on the phone which is showing the X cross. Press F12, contact detail will come up. Click on the contact no. and check the mac address is it correct.
