Yeastar S100 and T54W BLF visual alert name LDAP

[gugaua]

Hello,

I am trying to achieve a name lookup through LDAP on my T54W.
If my extension is beeing called directly from SIP Trunk, I can see the name, which is lookup up via LDAP from Yeastar LDAP Server.

If another extension that exists on T54W-BLF is beeing called I can see only a number without a name

What do I need to do to change this behavior?

This is what I have set up beside LDAP
features.pickup.blf_visual_enable = 1
features.pickup.blf_audio_enable = 1
account.1.alert_info_url_enable = 1

Thanks in advance
