[FAQ] Can Poly phones perform a reverse number lookup?

[SteffenBaierUK]

UC Software 6.1.0 added the RNL/ Reverse Number Lookup feature for compatible phones.

An example configuration could look like this:

<?xml version="1.0" standalone="yes"?>
<!-- Enable Reverse Number Lookup -->
<!-- up.rnl.priority -->
<changes>
<test up.rnl.priority="Ldap,SIP,Local"
                voIpProt.SIP.CID.request.sourceSipMessage="INVITE"
                voIpProt.SIP.Caller.SourcePreference="P-Asserted-Identity,Remote-Party-ID,From"/>
</changes>

Simply import the attached via the Phones Web Interface and configure a working LDAP configuration to use this. Please ensure the LDAP configuration includes the phone number to be search able via:

dir.corp.attribute.3.type="phone_number" dir.corp.attribute.3.searchable="1"
