Hi Tihomir,

When installing SylkServer from development branch you must install manually the required dependencies:

 * python-sipsimple (>= 0.20.0) http://sipsimpleclient.com
 * python-sqlobject (>= 0.12.4)
 * python-twisted-words
 * python-wokkel

I was trying to find some good documentation on that, but so far nothing. The default configuration files are fairly simple and I believe I had everything configured properly there. What I have currently is a whole working OpenIMS environment where SIP/MSRP messaging works OK. Then I have configured the OpenIMS ENV to route the messages towards the SylkServer which happens btw. However what I see is that the SylkServer tries to route the messages back to the OpenIMS, e.g. does a loop.
