Hi Bogdan I could reproduce the problem on lab. This is the scenario:
A INVITE -> OPENSIPS OPENSIPS INVITE -> B OPENSIPS <- B 200 OK A <- 200 OK OPENSIPS This 200 OK is lost or discarded on A, not sure if was on network or problem at client. Then: A CANCEL -> OPENSIPS A <- 200 OK (of Cancel) OPENSIPS Then the call is up for ever. Here is the log at the moment the CANCEL is received: https://pastebin.com/79qanD2H And PCAP: https://drive.google.com/file/d/1lpHWN1uRD1SOwBTZdijSodXBWhUX-rM8/view?usp=sharing Can you help?
