[SIP Beyond VoIP] Sylkserver – I'm too stupid to understand the sparse documentation

Thanks for the help Adrian. It's still not doing anything useful, but some SIP and XMPP messages are exchanged.

When I try to call a user in the sip domain from an xmpp client, no SIP messages are sent to or received by the SIP server (according to sip_trace.log and the Asterisk console). Any idea what could be wrong? 

from xmpp_trace.log (I replaced the real domain with example.net):

srv records are configured properly

in xmppgateway.ini I only changed
domains = sip.example.net

The request arises as INVITE to to SylkServer which then routes it to XMMP application based on the login configure (by domain of URI, or set xmpp-gw the default app so that all requests go to XMPP)
