Ok, this is getting really weird:
I can make calls from comp1 via proxy to comp2 (twinkle, ekiga clients).
But I cannot make calls from HPsip phone to comp2 or comp1, because I get initial loose-routing rejected.
As I understand loose router separates the destination of the request from the set of proxies that need to be visited along the way of call.
So it could be the problem with broken client?
