We are currently experiencing problems with our production OpenSER (1.1.0) environment where the load on the server is steadily increasing and the OpenSER response time increases drastically (e.g., 30+ seconds for an internal call to ring).
Capturing the network traffic when this happens we have noticed that our Asterisk (1.2.10) voicemail server is sending malformed CANCEL requests to our OpenSER proxy. We are not certain whether this is a cause or an effect of the load problems on the OpenSER server. Here is the SIP data from the bad CANCEL request:
I just want to close the loop on this issue in case anyone else runs into this problem. Thanks to the advice from Vadim Berezniker we are using the attached patch applied against Asterisk 1.2.18, which eliminates the bad CANCEL requests (no longer missing the sip prefix).
