LDAP Global Addressbook

How it works

Every time a user starts to dial a number or name on the Snom phone, an LDAP lookup is sent to the openLDAP server asking for "cn", "telephoneNumber" and "displayName". Any entry in your LDAP tree which has a telephoneNumber is displayed by the Snom phone. If the user is typing in a number then the results where the "telephoneNumber" begins with the digits dialled so far are shown in a list. If the user is typing in a name then the results where the "displayName" (or "cn" if "displayName" doesn't exist) matches the characters dialled are shown in a list. The search is not case-sensitive.
Use the up and down arrows of the silver navigation button on the phone to scroll through results.

Phone Configuration

  • Server Address: enter the name or IP address of the server with OpenLDAP running on it.
  • Port: 389 is the standard LDAP port and OpenLDAP uses this by default. Make sure there are no firewalls blocking this port.
  • Base: this is the suffix setting configured in the slapd.conf file on the OpenLDAP server. E.G. "dc=provu,dc=co,dc=uk".
  • Username: this is the bind DN. For example, if there is an inetOrgPerson entry with "cn=Paul Hayes" inside an organisationalUnit called "Staff", this setting could be - "cn=Paul Hayes,ou=Staff,dc=provu,dc=co,dc=uk".
  • Password: this is the userPassword attribute for the DN specified in the above setting.
  • Max Hits: maximum number of results to request.

Zyxel 660 HW SIP incompatibility

Zyxel have included a Application Layer Gateway in the 660H series adsl modem/routers.  Unfortunately this SIP-ALG breaks  SIP Voice Over IP!

 

Even more unfortunately you cannot turn it off from the web interface.

 

 The fix is to logon to the device via telnet and enter the following command:

 

ip nat service sip active 0

 

You will receive the response:

 

SIP ALG Disabled

 

Reboot your modem/router and the SIP device, you should now be able to make and receive calls.
