displayname PSTN to Jabber

[aherz123]

when we make call from PSTN to cucm to Jabber CSF, the number appears on jabber as the following: number@cucmhostname

how can we remove the "@cucmhostname" from the display name?

@aherz123 In CUCM (any node), go to System > Service Parameters. Select A CUCM / Cisco CallManager service. Under “Clusterwide Parameters (Device - SIP” make sure the “URI dialing display preference” is set to “DN”.
