If you are using Jabber/XMPP but haven’t been able to convince your friends yet, you should get them to use http://Quicksy.im instead. It will only take them 60 seconds to sign up and contact you on your regular XMPP address.
Why can #quicksy not implement the #addressbook like in #signal?
See this post:
"In regular intervals Quicksy will upload a list of phone numbers from your Android Address Book to the Quicksy Server and get a list of matching Jabber IDs in return."
With this, I can also use #whatsapp & get access to all contacts...
I don't see a way to download?
