Contacts/LDAP
Contacts can be created in the PBX and managed in contact groups.
When the LDAP server is activated, these contacts or contact groups can be transferred to phones connected to the PBX, provided they support it.
Auerswald/FONtevo provides LDAP support for the following IP end devices:
IP telephone
COMfortel 1200 IP
IP telephones
COMfortel 1400 IP / 2600 IP / 3600 IP (from firmware version 2.4A)
IP telephones
COMfortel D-100/D-110/D-200/D-210/D-400/D-600
IP DECT phones
COMfortel M-5x0/M-7x0 via IP DECT base stations COMfortel WS-500S and COMfortel WS-500M
*Note: Data is sent to D-series telephones via LDAPS, in encrypted format.
Contact data 
Detailed information about a contact can be saved in the contact data:
•Name of a person and/or a company
•Display name to be displayed for incoming calls
•Additional information such as department, position, date of birth
•Phone numbers, different e.g. for business, private, mobile
•Addresses, different e.g. for business, private
•E-mail/Internet addresses, different e.g. for business, private
•Contact image to be displayed for incoming calls in addition to the name
*Further help under Incoming Calls
Contact data can be adapted and extended as desired, regardless of whether they were created manually, taken from the call data list or imported via vCard or CSV.
The only exception: contact data existing through synchronisation with a Google account cannot be edited.
*Important: The synchronisation with a Google account is only available with feature level 2 or higher. If you want to use this function, please contact your dealer or system partner.
*Further help under Feature level
Contact groups (PBX/Google) 
The contact groups serve to manage contact data. For example, to organize large address books by department, the contact data can be assigned to different contact groups. Contact data can be made available to the connected telephones (if supported) via LDAP, separated according to contact groups.
The PBX distinguishes two types of contact groups:
•PBX
Allows free assignment of contacts created manually, taken from the call data list or imported via vCard or CSV.
•Google
Allows synchronisation with a Google account.
*Important: For certain requests when synchronising with a Google account, the COMtrexx now requires access to the Auerproxy server. Make sure that the address and port are reachable.
*Further help under Network
*Important: The synchronisation with a Google account is only available with feature level 2 or higher. If you want to use this function, please contact your dealer or system partner.
*Further help under Feature level
New contacts are automatically assigned to the assigned default contact groups as soon as they are manually created, taken from the call data list or imported via vCard. However, contacts that have been created by importing a contact file (csv import) are not automatically assigned to a standard contact group.
*Note: If a large number of phones are connected to the PBX, or large volumes of contact details are to be uploaded, it may in certain cases take several hours before the contact data is available to all the phones after the PBX has been commissioned.
LDAP server 
The LDAP server is needed to transfer the PBX's contact data to those IP end devices which support this transfer method (e.g. SIP phones with LDAP support). Any contact data that is input directly on a phone is not transferred to the central contact files.
The LDAP server's IP address matches the PBX's IP address and is predefined.
When switched off, the security and performance of the PBX are improved. No contact data can be transferred to the IP end devices.
Enter the following values into the IP end device to transfer the contact data from the LDAP server of the PBX to the IP end device:
Selected contact groups (e.g. in the factory settings)
Username
cn=auerswaldschandelah,dc=auerswald
BaseDN
dc=auerswald
Password
automatically generated password
Contacts for individual users (e.g. for the internal number 31)
Username
telephoneNumber=user number,dc=auerswald
BaseDN
dc=auerswald
Password
User password of the user
*Note: You must enter the complete character string. Ensure you type the capital and lower-case letters correctly, and do not type any blank spaces before or after the , and =space.
*Note: In order to avoid input errors, on the web interface in the lines below the entry and list fields you can mark and copy the user name and BaseDN.
*For more information on data exchange with the LDAP server, take a look at the Privacy Policy of the COMtrexx. You will find this in the Internet under: Auerswald Support/FONtevo Support or here: Dashboard > Status information > Legal > Data protection
LDAP proxy 
Internal telephones can also access an external LDAP server via the COMtrexx used as an LDAP proxy. LDAP requests to the external LDAP server are then made by the COMtrexx. The external LDAP server must therefore only be accessible from COMtrexx, but not from the telephones.
The configuration data in the IP end device (access information, filters, search areas) is based on the specifications of the external LDAP server. Only the address and port of the LDAP server point to the COMtrexx. Existing provisioning files must therefore be adapted.
Simultaneous use of the COMtrexx's LDAP server is not possible. In order to continue to supply internal telephones with the internal telephone numbers, these must also be managed in the external LDAP server.
