Contacts
These setting include:
Locally stored contacts
Contact details received via Exchange
Contact details received via LDAP
Contact details received from Google accounts
*Note: Changes in Exchange, LDAP and Google 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 alphabetical order in the contact list.
Contacts with whom you communicate frequently can be marked as favourites and thus displayed first.
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.
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.

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.
Occupied 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

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.
