Openfire Asterisk plugin - unregistered phone mapping

Hi all,

could somebody please help me ? I am already fighting 2 days to make asterisk work with openfire. Everything is new install (default)

Debian wheezy

Asterisk 1.8.13.1

I could add the Asterisk server without any issue in Asterisk-IM plugin, but when i try to add a Sip phone mapping, it says unregistered. When i hit test button, it says it is working - i can see it in asterisk logs, it just keeps saying unregistered, and i am unable to use the client.

Any ideas ?

Thanks

kind regards
