Contacts
These setting include:
•Locally stored contacts
•Contact details received via Exchange
•Contact details received via LDAP
•Contact details received from Google accounts
•Contact details received from Outlook accounts
•Contacts of the device
*Note: To access the device's contacts, the app needs authorisation. This authorisation was granted during the initial commissioning of the softphone or can be added later. You can usually find the authorisation settings in your device's privacy or app settings.
*Note: Changes in Exchange, LDAP, Google and Outlook contact data are not automatically updated in the softphone. The update is done manually in the softphone or by restarting the app.


Stored names are retrieved and displayed in
•Calls/conversations
•Softphone lists for contacts, calls, messages, voicemails


All contacts are displayed in the contact list sorted by first or last name (see settings).
Contacts marked as favourites and contacts with subscription enabled are grouped and moved to the top.
Exchange 
The softphone allows the retrieval of contact data of one or more Exchange accounts. Only the user's contacts are imported. Alternatively, the public contacts can be retrieved from the Exchange server via LDAP.
The information about an Exchange contact is not stored in the softphone configuration. When accessed (e.g. when starting the app), all contacts are downloaded, saved and are available locally until the app is restarted or the contacts are next manually updated.
Various local extensions/changes can be made in the softphone, which then become part of the softphone's configuration.
*Note: Querying Exchange contact data is only possible if the softphone has access to the Exchange server via the network. If this is not the case, the Exchange access data should not be set up.
*Note: If the softphone temporarily has no access to the Exchange server, the most recently loaded contacts remain visible in the contact list with their name and phone number. These contacts may be out of date and are only updated the next time the Exchange server can be accessed.
LDAP 
The softphone can be provided with the PBX’s contacts/address books via LDAP (Lightweight Directory Access Protocol). Depending on the support of the PBX, the LDAP contact data also includes internal numbers for subscribers, groups and emergency calls.
The information about an LDAP contact is not stored in the softphone configuration. When accessed (e.g. when starting the app), all contacts are downloaded, saved and are available locally until the app is restarted or the contacts are next manually updated.
Various local extensions/changes can be made in the softphone, which then become part of the softphone's configuration.
If the PBX's LDAP server is enabled, the LDAP access data is provisioned when the softphone is set up. No further settings are necessary.
*Note: Querying LDAP contact data is only possible if the softphone has access to the PBX via the network. If this is not the case, the LDAP access data should not be provisioned (PBX). Access data that has already been provisioned can only be deleted using the backup function.

*Note: If the softphone temporarily has no access to the PBX, the most recently loaded contacts remain visible in the contact list with their name and phone number. These contacts may be out of date and are only updated the next time the PBX can be accessed.
Google 
The softphone allows the retrieval of contact data of one or more Google accounts.
The information about a Google contact is not stored in the softphone configuration. When accessed (e.g. when starting the app), all contacts are downloaded, saved and are available locally until the app is restarted or the contacts are next manually updated.
Various local extensions/changes can be made in the softphone, which then become part of the softphone's configuration.
Outlook 
The softphone allows the retrieval of contact data of one or more Outlook.com accounts. If you do not want to see all but only specific categories of an account, set up the same account multiple times, each with a different category.
The information about an Outlook contact is not stored in the softphone configuration. When accessed (e.g. when starting the app), all contacts are downloaded, saved and are available locally until the app is restarted or the contacts are next manually updated.
Various local extensions/changes can be made in the softphone, which then become part of the softphone's configuration.
*Note: Favourites are not imported from an Outlook account.
Busy status/presence status when Subscription function is enabled (COMtrexx) 
When operated on a COMtrexx, the softphone supports the SIP functions BLF and Presence. If the Subscription function is activated (possible separately for each contact), the COMtrexx sends the busy and presence status of the internal phone numbers to the softphone. The following information is transmitted:
•Call or conversation status
•Do not disturb enabled
•Call forwarding immediately enabled
This information is displayed on the following pages of the app:
•Dialling
*Description of the operation and display under Dialling
•Contacts
*Description of the operation and display under Contacts Overview
Video feed 
A contact can be assigned an IP camera that is publicly accessible or set up on the local network. This will be displayed instead of the profile picture during calls and conversations. This means e.g. that calls from the door can be linked to a camera on the door.
Door functions 
If a contact's phone number is assigned the number type Door, four further phone numbers of the number type Door Bell Button are automatically created. For an incoming call via one of these phone numbers, it is displayed which door bell button was pressed.
For the phone number with the number type Door, a function code for opening the door and a function code for switching on the door light can be stored. Both actions are available for incoming and outgoing calls as well as during a conversation with this contact.
