Contacts: Unable to import contacts to AVM Fritz!Box-Router via CardDAV

Created on 18 Jan 2020 · 5Comments · Source: nextcloud/contacts

There's a new feature for the Routers called "Fritz!Box" by AVM (German devices).
You can import now CardDAV-Addressbooks for use in your home-telephone-devices.
Great - very nice, but it does not really work. Here the result:

Import from Nextcloud 17 / Contacts 3.1.6:

Import from Apple's iCloud:

Here's the Contact:

Hm, The FN: field has the full name with the last name first, followed by the given name, separated by a comma. I think the comma has to be escaped by a ' \' in the raw VCARD text to indicate that it belongs to the string to be displayed. However, the FN has to be unescaped (i.e. the '\' removed) when it is displayed.

So I think it's OK if the comma is in the VCARD text itself, and it _might_ be a problem in the Fritz!box firmware that it doesn't unescape the FN when it reads the VCARD.

Please note that the order of the first name / given name is different in your screenshots for NC and AC. Is it possible that the FN is stored as "Adler, Karen" in NC, but as "Karen Adler" in Apple Cloud? In this case the FN field from AC includes no comma that has to be be unescaped before being displayed, so of course this looks right if the bug is in the FB firmware.

Just a few thoughts from another NC user.
