Description
The cards from the Contacts app should be queryable by an XML API.
Use case
On compatible business IP phones (for example Gigaset N510), search Nextcloud contacts by name, and have the phone display their name (reverse query on the phone number) when they are calling.
I don’t think that this is the primary focus of Nextcloud because the address book core relies on CardDAV. Therefore I would recommend to customize e.g. the following tool to export data in the format your phone is expecting. That’s the way how I personally solved it for different devices.
Thanks for the hint, the script to convert from CardDAV to XML phonebook sounds like a reasonnable solution for now.
The phones also have also support for LDAP addressbook (with fullly customizable queries), but I don’t think it would be easy to implement a PHP based LDAP server in Nextcloud.
Hi!
Like @j-ed said, we’re using carddav as backend, so we won’t have any solution for your xml issue 
Sorry!
Cheers, John.
I’ll let you two discuss if you want.
