Found similar question in archives - so workarounded with $ru modification. Thank you!

Well, I found problem. The resumed INVITE transaction was sent to LOCATION route instead of RELAY.

However I see another problem now - t_relay() attempts to send resumed transaction to bad destination address.

I tried to workaround it with t_relay_to_udp/tcp/tls(ip, port) However kamailio reports function t_relay_to_udp: parameter 1 is not constant

The problem line is: if (!t_relay_to_udp($var(rr_ip), $var(rr_port))) sl_reply_error();

Does it mean t_relay_to_udp() accepts only constant values?

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.
