[SR-Users] t_suspend()/t_continue() problem

Greetings. I'm trying to adopt kamailio to handle incoming calls / generate push notifications for softphone running on Windows Phone 8. Starting point was this publication http://www.kamailio.org/events/2014-KamailioWorld/day2/26-Daniel-Constantin… I adopted the script from publication a bit - now notification URI is extracted from REGISTER messages + INVITE transactions are not resuming when unregistering happens. However it does not work for me yet. I see the suspicious output in kamailio log when softphone registers after incoming push notification. Please ignore ERROR: level name - it is just dirty logging call, not real problem.
