LDAP filter (sn>=0)(sn<=zz)



we are using Polycom 331,450,650,6000 and 7000. We also use LDAP directory.

Every time when a device sends a request to LDAP server, in the filter there is "&(sn>=0)(sn<=zz)" for example:

Filter: <(&(sn>=0)(sn<=zz)(|(sn=S*)(givenName=S*)(telephoneNumber=S*)))>


I want to omit the &(sn>=0)(sn<=zz). Is it possible?


Also, do you have any manual how can I set up the dir.corp.attribute.x.filter?

In every example there is only:



I tried to use eg.:



but nothing changed in the filter send to the LDAP server.


Tested on last FW 4.1.1 and on 4.0.8


Many thanks,


Jakub Zima

Just one comment.
In my LDAP server I have those contacts:

Libor Jedle

Libor Smrček

Libor Šosna


with this filter "Filter: <(&(sn>=0)(sn<=zz)(|(sn=libo*)(givenName= libo *)(telephoneNumber= libo*)))>" LDAP server will reply only with names:

Libor Jedle

Libor Smrček

Hello @jaqup ,


Welcome back to the Poly Community.

UC Software 4.1.1 is for LYNC only and not for openSIP devices. UC Software 4.0.14 or after the weekend UC Software 4.0.15 is the latest for these phones.


The LDAP FAQ here:

If you still struggle, and other community members have no extra ideas, the next step would be to open a support ticket.


In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
