I tested Mobicents (RestComm) Sip-Servlet (v 4.0.21) in proxy mode. Request "CANCEL" sent from UAC to UAS via Proxy Server (Apache Tomcat 8.0 + MSS 4.0.21) is not forwarded to UAS. The Sip-Servlet just returns 200 Cancelling to UAC and calls proxy.cancelAllExcept.
What could be reason of such behavior?
Thanks, David
The problem was somewhere related with ipAddress in SIP Connector section of server.xml. It was 0.0.0.0. As soon as I put IP4 returned by ipconfig the sip-servlet behavior became as expected.
