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).
