Connect Fritz!Box to Jami Servers (maybe via SIP Servers?)

So I was setting up my old Fritz!Box - and I was wondering, if it could be possible to connect my fritz!box to my jami Account and let my landline ring.

This would also be wonderful for my family.

All the best,

Jami is also a SIP client and you should be able to configure a SIP account with your Fritz!Box

where do I find a howto?
