Definite one. SyncML ist the standard in many newer phones and syning my phone/pda with my groupware is a prime productivity issue...

*** This bug has been confirmed by popular vote. ***

I think this is an issue of increasing importance for industrial use
of KDE. Funambol would be another example for a server.

The sync thing already works with Kontact and eGroupware, you can also sync your WM-phone with the funambol-client to/from eGroupware.
Just a few issues/limitations described here:
http://bugs.kde.org/show_bug.cgi?id=180564

Anyone interested in having a KDE centralized sync tool should vote for this wish:
https://bugs.kde.org/show_bug.cgi?id=107681
I put my vote behind this wish. However it does not seem to be adressing the need for direct sync with a pda/phone device, only with a syncml server.

On that other wish mentioned above I made a comment that talks about Sync Evolution because it's on the way to become a more feature rich tool
(direct sync and server sync) thanks to intel funding its developer Patrick
Ohly (see
http://www.estamos.de/blog/2009/05/13/syncevolution-09-beta-1-full-time-project-using-synthesis-syncml-engine/).
"While the project is currently mostly targeting Moblin+Evolution, it was
always meant to be open for other contributions", quoted from
http://www.estamos.de/blog/2009/07/01/gran-canaria-desktop-summit-2009-talk-about-syncevolution/

So how about joining forces and taking advantage of the momentum?
I'm putting my vote behind this and hope others will follow...

together with the Funambol-Server Akunambol should do the job:
https://projects.kde.org/akunambol

For my needs Funambol is overkill - I'd prefer to use syncEvolution's builtin syncevo-http-server

Hi,

for quite some time i use syncthing on my Linux desktops as well as my Android phone and 
additionally KDE Connect for data exchange.
I gave up finding a proper solution for syncing addresses, phone numbers and calendar events, 
thus no longer wish for a solution via SyncML

BR
